RP...These are my thoughts.
Beer
I pretty much agree with Karen. The best beers I've had are Hoegaarden, Guinness Draught, and Stella Artois.
Cocktails and harder drinks
I suggest Malibu since you're novest. It's made to get chicks drunk, fruity and good. Cocktail wise, Blue Kamikaze or your traditional Screwdriver, both good tasting and getting girls drunk friendly.
Personally, my choice of cocktails are anything with Bailey's and/or Kahlua in it, especially the B-52.
Whiskey Sour is good too.
Shots
For the girly stuff go with soco or a buttery nipple (tastes like butterscotch, pretty damn good).
People will probably push Jack Daniel's on you, well at least that's what I found in Bars. Cheaper than most shots, doesn't taste very good, but gets the job done very nice.
As for me, I go with sambuca, soco, scotch, or tequila.
Anyhow, that's my two cents. Karen and Necromunchkin are probably the best to listen to though, they know their alcohol pretty damn good.
Though, sorry Karen, Draught>>>>Stout by miles. Ewww at Stout and Extra Stout. I'm Irish, so listen to me on this one.
