Might want to check out
Mad Electrical - he might likely have something for your battery. But you'll have to call him up and I would expect a long chat (he is a talker but all great information).
Not only is there is there a relay upgrade for headlights but for the starter too.
As for headlights, I do like my
Dapper Lighting OE7-Glass LEDs... closest I could get to a stock look with LEDs.
