Mine is a little long, so I pastebinned it: http://pastebin.com/niPiPUsf
A lot of stuff is still standard, except for moved key binds. I've just tried to use other binds like any-weapon ubers, but I just can't get used to it. There is still a lot in there that can be useful.
As for huds, I use EVE HUD. It's a nice, clean HUD that keeps the TF2 look (if you like that, that is). It also has an option for a centered Ubercharge bar, which is INCREDIBLY useful. If you get anything from this, it better be that you should find a HUD with a centered Ubercharge bar, because it allows you to stay focused ahead of you more than one in the corner. It's saved me more than once, where I'm close enough to a saving Uber and I can simultaneously look ahead and see just when I'm charged.
