Most of the places around here believe that Bud, Miller and Coors is all that is needed. Sad.
Grinders is pizza joint with something like 20 taps. They always have some great beers. they are somewhere near 18th and Oak or Vine or something like that. Some of the fancier pizzas sound interesting, but are nasty. Take a cab. The area gets dangerous at night.
I would avoid River Market. There beer is inconsistent.
Power Plant is in Parkville, Gorden the brewer is a good guy. He sometimes makes a dark wheat with Chimey yeast. I think they have 6 taps, all good beer.
Waldo Pizza has a good beer selection, even if it is a little pricey. Great Pizza. Don't miss the Katie Trail Pale Ale.
75th Street kicks ass. They had a big fire earlier this year on their block and suffered smoke damage.They should be back open by the time you get here.
As far as buying bottles of beer, Lukas Liquors on 137 st and State Line can't be beat. I think they are up to 650 to 700 bottles. Here is a link to the beer guys blog
