This is another question best answered by a salesperson in one of your local ski shops. This is a question that isdefinitely not a question someone can answer on wikianswers, because skis that are 150cm may be way to long for one person and skis that are 175cm may be way to short for another person. The size of the skis you should buy depends on a lot of things, such as: height, weight, skier ability, and style, power or finesse. For me, skis that are 161 are about right. I am 160lbs, 5'6" (I'm A LOT heavier than I look) I ski aggressively, my style is more towards power, I'm type 3 skier and ski all mountain (I put in the correct info onto a ski calculator and got the length). For comparison I put the same height and weight into the calculator but said the style was more finesse, skier type 1, doesn't ski aggressively, and sticks to groomers and the length this time was 155cm, just goes to show that height and weight are not the only things that matter. This is a fairly good ski length calculator so I will give you the website address, http:/www.frostyrider.com/tips/size-guide-skis.htm (copy and paste into the address bar of your computer). This is a good site but nothing beats the advice of a skier who is trained in helping people find the correct size skis. My best advice would be to go to your local ski shop and ask them, they will be able to answer.
As a general rule, the better the skier, the longer the skis. Talk with the sales people at a good ski shop, and they will help. In other words, don't go to the 'bargain ski world' at Walmart.

In ski racing, downhill skis are the longest, but slalom skis are the widest.
over 100mph at least
Yes, skis WILL help you get downhill faster if there is snow. You need to know how steep the hill is to know how fast you will go. If you add some ski wax to the bottom of your skis, you will go extra fast.
The average length of downhill skis ranges from 150-200 cm, with width typically around 80-100 mm at the waist. Downhill skis can reach speeds of 50-60 mph (80-97 km/h) depending on the terrain and skill level of the skier.
When you store downhill skis over a long period you should put a storage wax on. This is a special wax designed to keep the bases from drying out and cracking. A good place to store your skis would be a place that is cool and has a medium humidity. Too dry will dry out your skis. Dark is also good as bright sunlight can damage the graphics and will make the temperature rise and fall which will also damage your skis.
if by regular skis you mean downhill skis, then longjump skis are similar, but they are nearly twice as long and twice as wide-- the greater surface area makes the ski jumper accelerate faster, thereby allowing him to travel farther off of the jump
Quite a bit is different. The gear is different, the skis are straight, as opposed to downhill skis being curved (the curve makes it easier to turn on a downhill slope), the boots in cross country are not stationary in the bindings, as downhill boots are, instead you can move the heels, and the poles used in cross country are longer. Also, the slopes are not nearly as steep as in downhill skiing.
Well that kind of depends on what you're doing on them. Generally speaking, longer skis are more stable, hence highspeed downhill racers use longer skis. Shorter skis are more manueverable and easier to make tighter turns on. There are other factors such as width, shape, and flex of the ski that play into the equation also.
Not unless you are a ski racer yourself, and were lucky enough to get top of the line equipment. World Cup skiers get the best race skis that their factory makes. They have many different pairs of the same type (downhill skis, for example) that they will test to see which are the fastest. Race skis are highly specialized and differ greatly from demo skis or skis that the public usually buys. You can see this reflected in the price. Race skis typically run $800-$1000 for the skis, not including bindings.
No, the ski format is used with skins to climb up mountains, not for going downhill. You go downhill in board format. Then back up again in skins with ski format.
Alpine Touring, also known as Randonnée, is a type of backcountry skiing. Randonnée ski bindings are a cross between standard downhill bindings (toes and heels locked in) and telemark bindings (only toes locked in). With randonnée bindings, the skier can clip down the heel piece when skiing downhill (like downhill bindings) and release it when skating or climbing (like telemark bindings). Special ski boots are used with both telemark and randonnée; though, randonnée boots have rigid soles like standard downhill boots. Also, randonnée bindings can release during falls, but telemark bindings cannot. And a skier need not learn to turn differently on AT skis, as with telemark skis, since the heel can be clipped down. As for the skis themselves, AT skis are typically much wider and heavier than a basic ski-area ski, as they are used more often in deep powder and ungroomed conditions; though, randonnée bindings can be mounted to most skis. All Mountain skis are a mid-width type of ski, such that the skier can handle well in both groomed and ungroomed/powder conditions--the latter not as well as with AT skis.
