Hello,
Do you guys think the following lenses are a good base point?
Tamron 28-75mm 2.8 for everyday use
Sony 85mm 1.8 for portraits
Sony 50mm 1.8 for everyday use also
Thoughts?

You've gotten a lot of good advice so normally I'd say go with what your gut tells you. And I really don't want to throw a wrench in the works. However...
...you've indicated budget constraints (having to sell the Canon equipment) and unless you have other equipment not listed, it appears you've only shot with a standard (f4) zoom. So, unless you're in a rush, why not just use the 28-75 for a while and see what you're lacking - with the f2.8, you'll get decent separation and low-light performance and it won't be terrible for portraits, at least in the short term.
Of course, if you're pretty sure you're going to do a fair amount of portraits, go ahead and get the 85/1.8 - not that expensive and you may regret not having it. Or the 90, as suggested above, though it is a little more expensive.
The one I'm struggling with, given your constraints, is the 50/1.8 - not sure how it adds, right now, to what you want to do, unless you're looking for a really light walk around lens. Sure, it's pretty cheap, but how often are you likely to switch to it when the 28-75 is on your camera? Or vice versa? A lens that never gets used is, ultimately, pretty expensive.
In any case, hope I'm not screwing up your thinking too much. Good luck with your decision.
