If you are a going for bones bearings make sure you try to find bones swiss. Easily the fastest bearings i've rode with.
If you mostly just want to do tricks, a smaller board is going to be better for that.
I'm not sure what your budget is, but for like $20 more you could get a LIB deck and they have free shipping right now.

OK cool...8 inch should be good then. For the most part, grip tape is the same. I wouldn't worry about which brand you got just as long as you like the design/color.
