1.) Is 64 bit Vista any faster? It's not that the x86 version is slow, it's just that if there's a benefit to the x64 version why not use it since I'm not playing games and can't imagine any driver issues.
The only true benefit of x64 Vista over x86 is the fact that Windows will see past 3GB of RAM. With x86, Windows only sees just around 3GB, and that includes virtual memory. It's not faster or slower. Though if you're going to get a new OS, I would go x64 at this time because I guarantee you in 4 or 5 years or so, stuff is going to want that much RAM and you'll be kicking yourself for not going to x64 sooner.
It's a transition period for sure, but you have to make the switch at some point. Don't be worried about drivers. I found 64-bit drivers for all my stuff: Logitech G5 mouse, Logitech QuickCam Pro 5000 webcam, Xbox 360 Wireless Gaming Adapter, nVidia GeForce 8800 GTS, HP PhotoSmart C3180 printer, Gigabyte GN-WP01GS wireless network card, motherboard drivers, onboard sound drivers, etc. etc. etc.
I use Vista x64, and I've had problems, but nothing that was isolated to the x64 version. They were all just general Vista problems.
Can I ask you though, why do you want to switch to Vista? I don't recommend it at this point. XP is the superior operating system.
I was checking out a 64bit version of Vista and the main thing I noticed was it had trouble with certain applications. For example Photoshop CS3 refuses to work on it. I didn't bother with anything else after that since PS is my bread n' butter; without it an OS is useless to me.
That's weird. I wonder why that is because I use Photoshop CS2 with no problems. A Google search did turn up issues, but there is a workaround to get it to work:

I'm sure Microsoft Office would work on it though.
Yes, as I have said, I run Office 2007 Ultimate just fine.
