Lens questions for my fellow Luddites

[PJL]

I recently purchased a Minolta XG-M in great condition with three lenses for $50 (thank you, craigslist!)

As indicated below, I already have an XG-7, but the years haven't been kind to it; she still takes great shots, but there are a few cosmetic and small mechanical deficiencies, so I'm replacing it with the XG-M.

When I got the XG-7, I got the standard Rokkor 50mm f/1.7, along with an Albinar 135mm f/2.8 and a Panagor (sp?) 28-80mm f/3.5.

At some point, I also came into a Bullet 28-80mm that's stuck at 80mm, but has a macro feature.

With the XG-M, I got a Rokkor 50 f/2.0, a Minolta 135 f/3.5, and a Vivitar 70-210 f/4.5 macro.

First question: Is the image quality of the Minolta 135 superior enough to the Albinar 135 that I would want to lose the f/2.8 in favor of the slower f/3.5?

Second question: If you were going to come up with a kit of 3 lenses to carry for use on the XG-M, which three of the 7 listed above would it be? I want versatility, but more towards longer focal lengths.
