For the bottom bracket, your options are 1) reinstall a one piece crankset or 2) order a truvativ bottom bracket adapter and install it will a cartridge bottom bracket and 3 piece crankset.
As for the headset, genuinebicycleproducts.com sells a headset that lets you install a 1 1/8 threadless fork. This sells for about 50 bucks. Its essentially a 10 dollar headset that's been turned in a lathe to fit your headtube, but if you don't have a buddy thats a machinist its your only option short of installing the original headset and fork.
I will note that the site mentioned above also has aluminum seatposts that will fit varsity/continental.
Anyway, good luck with the build!
