find CG_LEVELTIMER in hud file.
it will have a parameter line most likely like : rect 111 222 0 0
forget the two zero's, 111 represent horizontal position and 222 vertical, ie height.
something like rect 290 32 0 0 should be around somewhere top middle.

This is the default HUD and you need to do the same thing as you did with your current HUD: put the files into the ui folder and go ingame and type \cg_hudFiles "ui/hud.cfg" and then type \loadhud and you've got it.
Also, you can't play with the item respawn timers. You can only use them on private servers while in spectator mode
