98 Grand Cherokee mods

Where do you guys buy your add-ons for Jeeps?Looking to do some off road lighting and maybe a few other accessories.Nothing crazy and it isn't getting lifted either.I have the tires already and I am good on the engine/exhaust side.Looking for the best deals and/or ideas of what you have done.
Thanks.

Edit;I wouldn't mind an opinion on an aftermarket header vs just going with a replacement manifold for power vs. cost/reliability.
