Ya dude I say get some tbolt clamps (from napa or wherever) for now and then worry about piping later. No need to stress about the hoses blowing off, you should be able to flog on it endlessly w/o that being a concern.
There's always a big list of stuff to want, but I think with a bit more maintenance and little stuff you'll have a solid setup to rock teh cones!
Did you hit the rev limiter yet?
