HI,
If iChat is Open and your think Accounts/Screen Names are logged in then go to the Window Menu
This should list the accounts that are logged in with various keystrokes ( Apple/CMD ( or ⌘) and a Number) shown next to them.
Using these should get the Buddy list "back".
It is possible to Hide the Buddy list and then Quit iChat.
iChat will then "remember" where the windows were eve if this was Hidden.
Can you confirm that after reinstalling or restoring from Time Machine with possibly an Earlier Version you have Downloaded the COMBO version of OS X 10.6.8 and "run the COMBO" (Installed it - again) to update iChat ?
It is possible the text chat Window is also Hidden on double clicking a Buddy.
The easiest way for this to happen is to use a second Display and drag some windows to the second Display.
iChat "remembers" where you last had Outgoing Chats so Audio and Video windows will be where you left them as will Text Chats.
Incoming Chat Invites are normally in set places unless there is a chat already open to that Buddy.
With  Windowing issue like this is sometimes pays to delete com.apple.ichat.plist itself  (on it's own) and restart iChat  (this plist holds the window positions amongst other things)
