mazda newbie questions...

Just bought a 87 mazda daily driver and have a few questions...
I know that the GMC wheels will fit and that its pretty common.... I bought the truck to be daily driven so but looking to get rid of the 14s. I will probably try to stick with GMC wheels for now. Are the wheels a direct bolt on or do they have be machined to fit?
 
Also, Im trying to maintain a lowered suspension for the time being. How do I go about lowering the frontend the right way? I know the back will either be leafs or blocks. I read people tightning down the torsion bars but I still want to maintain a decent (dont know if a minitruck can ride decent) ride.
 
I coming from a s10 background so the learning curve should be quick!!! Thanks in advance.
