New Beats are like industry standard, but I'd say go for 13", those with rippled bottoms (like Paiste Sound Edges), or vented bottoms (like Ziljdian Quick Beats)... these project the "hiss" better than 14" regular hi-hats.
Sa crash naman... 16 is a good size. Cymbals that have short decay are supposed to be thin ones, so I'd sa go for a thin or medium-thin crash (plus, they respond easily). A Custom is good if you really want it to project ("bright", like you said), but go for A's if you want it a bit warmer.
