I generally perfrom 3-4 exercises for a total of 10-12 sets. For bi's, I like standing cable curls (the EZ curl bar puts more stress on my biceps tendons for some reason), db curls, hammer curls, and concentration curls. For tri's, I'm a fan of pushdown, weighted dips, close grip bench press, and overhead presses. Usually, I'd spend about 2-3 weeks at sets of 10, then 2-3 weeks at sets of 8, then 2-3 weeks at sets of 6 and as low as 5. Then, I repeat that cycle. I've had good increases in size and strength over the years. I like the fatigue; I rest very little between sets.
