You can always sharpen later if you want to ...
You have a Macro Lens? I'm jealous.
Don't wait too long before trying out your Tamron, primes are a lot harder than zooms (personal experience).
Reviews for the Tamron look pretty good, I backed away from buying a Macro lens due mainly to the difficulty of good Macro technique (too much like real work) but also due to expense.
The magic number is supposed to 10,000 (Cartier-Bresson?) but I think it's like golf, fairly continual failure occasionally illuminated by one incandescent shot.
So many techniques go out of style eventually and maybe the bokeh I want to achieve with the macro lens will fade too by the time it is mastered. So maybe you are right to not bother with macro.
But there are so many interesting insects' knees and flower stamens out there.. :-)
