You need to be a bit patient, we are not paid to do this and remarks like that won't help.
Vista can be reinstalled using the same key on the same pc and hardware, although you may need to activate by phone, no big deal takes about 5-10 minutes. Chances are that net activation will go through.
As for Office without a key you're out of luck, surely you know how many pc's you've installed it on. It's not how many times you have installed it, but on how many pc's.
Formating a hard drive is fairly simple as long it does not contain an operating system or any system files from an instalation on another drive.
If it's a used drive, open the computer folder in Explorer, right click and choose format.
If it's a new drive, go into Disk Managment create a new partition, then format it.
