300 FPS is the standard/average speed, so yes that would be good. And the spring guns will last you awhile so yes, springs a good choice.
The FPS of that is probably going to be around 250 if you're using .2s but maybe I'm wrong, as the lower end weapons are getting stronger.
Another good option is to go to www.shortyusa.com and search the spring guns, then go by most rated. They have some cheap guns that are good.
Hopefully that helps a bit.
Distance, I can't tell for sure, around 100 feet maybe.
