Tough call. I really like the 135L on FF for portraits (I, too, started with an 85/1.8 on APS-C, then the 85L II, then when I got a 5DII, the 135L as well).
The 70-200/2.8 IS II is a great lens, does wonderfully for portraits, and 135mm f/2.8 on FF will give you the same framing and DoF as 85mm f/1.8 on APS-C. However, it's big and heavy so that may be a factor for routine use (that said, it doesn't bother me to carry it all day on a Blackrapid strap). But likewise, the 70-200/4 on FF will give you the DoF of f/2.8 on APS-C.
Are you keeping your 7D? If you'll continue shooting daytime sports, you should - the AF of the 5DII isn't really up to the task. That means you'll also still have the 17-55 as a general purpose zoom, but not have one for your 5DII.
Having said all of that, the 24-105L is a great walkaround lens for FF (better than the 17-55mm, since the FF-equivalent of that lens is a hypothetical 27-88mm f/4.5).
My recommendation - get the 5DII+24-105 kit, use the 85/1.8 (move closer) and the 70-200/4 for your portraits, and add the 135L when budget permits.
