Crank pullies post pretty good gains, but it is up to you to decide whether or not they are worth it. The way the stock Honda pulley is designed it dampens the vibrations from the engine, etc. and when you take this off it will take away from the life of your engine. This is effect is more noticeable with higher power/rpm's but either way in the end it will take away from your engine's life. Plenty of people have ran them for years and have had no problems but most of them are not running extreme set ups either. The other pulleys will work fine as long as you aren't running some crazy stereo set up or anything like that.

The battery is only used when the engine is not running, and mostly only for starting the engine.
