1. Will RDC allow me to actually see the PC's screen and use the programs on it?
2. There's a chance my PC at work is running XP (not Pro) and I was noticing that XP Pro is required for use with RDC. Is there a workaround for using XP?
1. Yes. You get a full screen (or a window if you want it) that's identical to your desktop. Your mouse becomes the Windows mouse while you're inside it, and everything looks like it would if you logged in locally.
Generally, it's pretty good about adapting to your native resolution (our Win2003 server shows up in native 1440x900 on my iMac), but if it can't, you'll get a full screen res that the Windows computer can understand with some letterboxing.
You can trim down graphical features slightly for speed, if you want to. When you're in full screen mode (with the beta), you can also still use Exposé (the full screen correctly renders as one of the active windows), and you can also use the dock, the OS X menubar, and OS X applications over the top of the full screen if you want. You can even dynamically change the fullscreen mode into a scaled (!) windowed mode (so you see a rendering of the full Windows screen in the window) in the beta. You can also cut and paste between Windows and OS X, and you can move files and share printers.
2. Unless you work in a very small company, it's pretty unlikely they bought Windows XP Home for business installations. But no, I don't know of a workaround, sorry. Might try googling about it, but I'd be fairly shocked if you're using XP Home at work.
Here's an example. If I click back into a window in Windows, the dock and menubar auto hide.
