front suspension nightmare

What started as a simple hub replacement has turned into a mess. I just put new tires on my 98 GTP and the place where I bought the tired offered a free alignment check...(side note, my car has had a vibration in the front end for a long time)

Long story short, wheels wont align, front hubs have to much play, bought new ones got home, found mess. Now I've changed the tie rod ends, drive axles (found leaky CV boot), and now I have the control arms off because the bushings on them looked trashed. I really hope that one of these things fixes my vibration.

I can't find the bushings at any auto parts store, so any advice on how to get those would be great.

Also, any advice on anything else to look for while i can see right in the transmission. I already bought new seals for the trans. for where I put the drive axles back in, and I plan to drain it out while I'm at it.
