A DA15, DA20-40 (or similar), and DA*50-135 is pretty much what you need at this point, don't you think? If you sell your other Tamron you'd basically have no lenses, right? I mean, you do want to take photos with it!
A few additions somewhere down the road could make sense, but you'll know when you need them. Obvious areas are a 300mm lens, a macro (can go cheap here if you want), possibly a fisheye or UWA, and possibly a prime or two around f/2 or faster.

That's scary Jatrax! I've owned all those lenses (or in a couple of cases their FA equivalents).
