multi-meter(digital), soldering iron(maybe a 25watt Weller), rosin core solder(small diameter). a soldering iron stand(the spring and sponge thing)
perhaps a de-solderer(or a copper wick), a small bread board to prototype your projects on and to help test them, a couple of different sized strip boards for making more permanent circuits on. some good quality wire strippers, some side dykes(dikes?), maybe a helping hands( has movable arms with alligator clips) good work space with ample lighting. some sorta fan to suck the solder smoke away from you(stuff's nasty).
as far as components go it all depends on what schematics you have for those three projects. get what ever parts they stipulate on them. hope that helps.
