Well, you are going to have problems... Sorry to say...
First off, most PCs with SATA drives will have an option in the BIOS to place it in IDE mode. This assures that Windows Setup will be able to detect it as a drive with the ability to be installed to.
As for USB drives, it all depends on your BIOS version and manufacturer. Toshiba for example, does not support ANY usb device unless it is made by their company. It sucks, yes, but i guess for more money for crappy products.
You can install the drivers to a flash drive, but you will also have to make a bootable image to that drive, and load your windows setup files, manually format and partition the drive, copy the files over, then start the setup process to do that. It is a huge hassle that I had to deal with on a Toshiba Portege 3500.
Backing up is a bit easier. You can use the built in windows backup software (Start>All Programs>Accessories>System tools> Backup) and make a complete backup to an external drive to restore after format. The problem is YOU WILL ALSO TRANSFER THE VIRUSES YOU HAVE!!!
If you use the file and settings transfer wizard, you can transfer most of your stuff, but you WILL HAVE TO REINSTALL A LOT OF YOUR SOFTWARE, as it will not transfer your registry entries.
Your best bet is to get an Antivirus/spyware removal tool (Such as www.superantispyware.com) and an anti MAlware software (such as Malwayebytes). This will clear most of your infections, and gives you more time to backup your files and get software discs ready.
