measure the diameter and thickness of the brake discs, compare to dba catalog, that probably will tell you what struts they are. mark from nz also has toyota strut measurements based on brakes, bolt hold spacing and steering arm measurements - www.toycrazy.net
starion wheels, they look pretty good, and would be wider than stock steelies, and probably most celica/torago alloys you can find. nice score!
starions are not really "common", but you can get them if you look, kinda like ke10s are
red springs could be pedders, fulcrum or koni off the top of my head
