Yes, infact it is recommended.

It depends on what you are going to use it for... If you are going to play more speedball, get the sonix... If you are going to play more woodsball, get the MR1.
Spyder Sonix can use any Co2 or HPA tank
any Co2 tank and high pressure HPA tanks.
You can use co2 tanks if they are the anti-syphon tanks or if you put that on your tank put even then they are not recommended.
Absolutely!
No, spyders use spyder threaded barrels, where tippmans use either 98 or A5/x7 threads.
My 2003 3.0 Litre eclipse spyder owners manual says to use premium with a minimum octane rating of 91,but you may use regular unleaded with a minimum octane rating of 87 if premium is not available.I've only used premium in mine and am very happy with results so far.
Any standard kit will be fine for a spyder.

Co2. Buying a Hpa tank for a cybrid is money that should be spent on a better gun.
