Do you think you could get a 3800 supercharger to fit a 3.4l or should i keep waitin for a kit?

a 3.8 s/c on a 3.4 could be tough. well, that depends on if you mean a roots type blower. if that's what you mean, there are other ones available that would probably be easier to work with. if you mean a centrifigul s/c, then about any of them could be adapted.

Me and a friend were looking were we could put a bracket because we know someone could make one for us, but what else would i have to worry about?

the 3.4 is a 60* motor and the 3.8SC (L67) is a 90* motor, the intake manifolds are different, although with some modification and some custom manifold adapters it could be done with the stock L67 manifold
otherwise youd have to make a special lower intake manifold

already a kit for 3.4l 4th gens, it probably will take very little work to get that working in a 3rd gen, if any.
main problem i can see would be any differences in the plenum/tb on the 3.4 if you kept your 2.8 stuff and put it on the 3.4. but i dont have any experience whatsoever with 4th gens, so dont take my word for it.

Anything can be done if you want to badly enough. You’d have to either fab up a manifold or some brackets and plumbing. Here are some pics of the M90 setup on my brother’s f@#d (while the car was being redone in a body shop):
