LoadingURL - Grabbing information from Steam servers

Right then,
I’m creating a Garry’s Mod server, and I have a custom loadingurl. It shows up all nice and neat. It tells me which file it’s downloading, etc… and it even converts the user’s 64bit steam ID to the more user friendly “STEAM_0:X:XXXXXX”.
I just want to know, what do I need to add in, to grab the player’s profile picture, and their Steam Name (not the username!).
Just need to tell me how to grab them, I can figure out error handling, and showing it up on the screen.
I know this will most likely need to pull up the XML info on the player, or to use the newer method of the SteamAPI key to grab this info (I’ve done my research, I just don’t know how to implement it.)
Any and all help is appreciated! Thanks in advance,

Sample code I’ve posted in another thread before http://forum.facepunch.com/showthread.php?t=1249168&p=39687209&viewfull=1#post39687209
