Yes. There is no law that prevents uncertified divers diving. However, most shops require some kind of training for liability reasons.
However, many organisations (including PADI), offer "discover Scuba diving" courses (sometimes referred to as "resort courses" because they are often done on holiday), which take just a half a day, and allow you to dive under the supervision of an instructor to limited depths.
You will need to train with a certified SCUBA company. PADI and BSAC are two of the best known. Try their websites for local dive clubs which will run training couses.
You need a wetsuit/drysuit, first and second stage apparatus, a snorkel (to save air), whistle/airhorn, buddy, certification, scuba tanks, and you would need a mask, defogger, and there is some optional equipment that you may need.
of course
You you either need a bathysphere or "scuba" equipment.
You can get a PADI certification at any PADI dive shop. The best thing to do is to contact a dive shop in your area and ask about their scuba certifications. If they do not offer PADI certification, they will likely know who in your area does. To find a local PADI dive center, just go to PADI.com and click on Start Diving, which will take you to the shop locater.
There are a few shops in Naples, FL that offer to opportunity to purchase scuba equipment, one of them is The Naples Florida Scuba Dive Shop which offers everything you would need to scuba dive.
There are no legal requirements to scuba dive. In other words, anyone can scuba dive without breaking a law (assuming you are not doing an illegal underwater activity such as illegal fishing). However, if you are not certified, you will not be able to rent or buy equipment or get someone to fill your scuba cylinder.
No, you don't need a certain body type to scuba dive. Because you use flippers to SCUBA dive, you can be a very lousy swimmer and learn to SCUBA dive. You may look stupid with a very tight wet suit during scuba diving, but you can dive. When I got certified, I learned that you have a very slightly higher chance of the Bends during scuba diving, but this is a small percentage. The pros of scuba diving outweigh the cons.
I am a scuba diver. To start SCUBA, you must pass training. Many training centers are available in many areas.
No, you do not have to go to college, but you do need specific training. They usually have this training at something like a YMCA or something similar. This training, while expensive, allows you to take multiple dives, lessons, and a test to get your diving certification card. This card allows you to dive, but you should never (I repeat, NEVER) go diving alone. This card allows you to get scuba gear and gas for scuba diving.

There is a store called Scuba Dive that sells equipment and gear in Ocean City
