Hey guys, i can answer these questions for you as I use Windows Vista Ultimate, Webguid, and the Q.
TV Card:
Any TV card that is recoginized and can be used in Media Center (the actual application that is built into XP Media Center Edition or Vista Ultimate or Vista Home Premium) will work for this application. Here is a list of compatible TV cards that work with Media Center.

Basically, any Hardware encoded MPEG-2 card will work with Media Center.
This program does work really well, as i have enjoyed it. It will stream all of your TV shows, videos, and music. i haven't tried pictures, but you might be able to do the hack so that websites won't automatically go to the mobile version and it should work. This program will also work using another computer on the internet. What it does is it sets up a webserver on your computer, and you actually log into your computer, and not a server that then relays it back to your computer like orb. Orb works great for something quick and easy for people that have an IP address that changes at home. If you use a router, most have a service for DDNS where you can signup for a static address, but will always point to your IP. This program really gives you control of Media Center remotely more than anything, and really won't help anyone out much without having media center.
if you would like to take a look at it, here is my webguid.
http://vistamce.homeip.net and the username is "guest", and the password is "guest" (both without quotes) that i'll leave open for a few days so that you can look and actually use it.... now, keep in mind, my upload is only around 300k, so you won't be able to stream or download the TV shows at any reasonable speed as they are usually over 6 gigs. but feel free to look around, and don't delete anything (which i don't think you can remotely anyway)
under the log in page, you'll see the go to mobile link, so you can also see what that is like.
also the mobile address is
http://vistamce.homeip.net/mobile even though it should be able to tell the difference, as it did with mine.
