For the liquor and liqueurs, that's a very good combo. Take what you will for the mixers and garnishes.
that's approx. 35 bottles, then beer and mixers/garnishes. Even at a steep avg of $35/bottle you'll have a few hundred left over for beer, mixers and garnishes. That's for a well mixed bar where you'll have lots of people.
For myself... pretty much whiskey, rum, vodka, a few liqueurs and beer. Maybe one-two mixers.
