First of all, iam just a member who uses this forum since today. I will provide some information that might help with your problems, though note that iam not a professional and that i cant and wont give you a 100% secure solution! I will just try my best!
Reading through your post I think you have already reinstalled vista, so there shouldne be any unsaved personal files on you pc. If not, save them somewhere else if you can.
Getting drivers back for a laptop can be quite a hazard. First you should check the toshiba site and get all the help and drivers you can for you laptop!
If you still miss some functions, I would get drivermax. Its a programm that compares your drivers with the drivers from other people on the net. drivermax will upload your profile to its servers and it will upload any drivers, which are newer than the ones in their database.
Also you can check for the newest drivers for your hardware via drivermax and download them from their database, note that downloads are limited if you are a free member! The limit is 2 per day!
I personally use the software to check for new drivers and then, if I cant find them on the net myself (ie nVidia and ATI drivers are easy to find) I use drivermax.
Another nice thing about the software is that you can export copys of all your drivers from you pc, so you can easily import them with drivermax after a reinstall.
Hope the information helped a little!
