New Lens Advice for A99v

So I went on a bit of a shopping spree, and I bought a Tamron 90-300mm, a Minolta 70-210mm 1:4 (32), and a Minolta Maxxum 50mm 1:1.7 (22). I've seen some positive reviews on here for the 50mm and the "Big Beercan", and I'm having trouble even finding out more on the 90-300mm. But do you guys think that for $250 total, I made a good purchase?

When people ask me whether I'm a photographer, I tell them that I'm more of a time artist. After all, my art is my ability to freeze time and capture a moment forever.
