Hi megrag, welcome to CiC!
While I can't comment on the bodies too much, your lens choice is ideal. I have the 50f/1.4 and love it - the 70-200 f/2.8L is the next thing on my list to pickup. I own the Pixma Pro 9000MkII and it is an amazing printer - I ended up getting the 5dmkII camera which didn't have the rebate for the printer - but the printer itsself had a standalone rebate (though not as much). Don't let the rebate sway you either way - pick the body off of the specs and how they relate to what you want to do. I would recommend that printer any day of the week though
Don't forget to budget for the accessories (i.e. tripod and external flash)!
Hope this gets you started, I'm sure others will be here soon to share their advice
