i would suggest, to minimize extra purchases, trying to go with a variant of one of the following:
American Pale Ale
Pilsner [using Pale instead of Pils malt]
since there will almost assuredly be specialty grains needed, practically all styles are still really available.
when i have a 'spare hop' problem, i honestly go re-read their descriptions, see which styles are listed in the most i have remaining...and then brew that style.
for bittering [full 60+ minute boil] you have a much wider latitude than you do with the flavor or aroma hops....but that Tettnanger for almost any continental style sounds amazing!
