Re: Cheap, fast standard prime lenses for the Nex 6?

Been busy at work so haven't had the chance to reply but I've been keeping up with responses
For a little update, went around asking older relatives if they have any old film cameras and picked up a kit from a person dropping photography so now I have the following:
Pentax Super Takumar 50mm f1.4, Minolta Rokkor MD 50mm f1.4, Vivitar 28mm f2.0 MC Close up (Komine ver), Vivitar 2x Macro Teleconverter, Tamron Adaptall 2 80-210mm f3.8-4.0 (03A ver)

Now for some questions...
1. The Pentax Super Takumar doesn't appear to have fungus but I see some black dots when looking through the lens but doesn't appear to be dust (didn't get adapters yet so haven't tested it yet).  Should I be concerned?
2. My Minolta just says Rokkor MD.  How does it compare to the Rokkor PG and Rokkor-X?
3. Reviews of the Tamron 03A are pretty bad so I plan on getting a different manual zoom later.    Would you recommend an Adaptall or a Vivitar Series 1?
4. Any must have lenses to pair with the Vivitar 2x Macro Teleconverter? 
Lastly, a big thanks for the many suggestions thus far..
