Newbie Here, 2004 Tacoma TRD double cab, Stock

I'm open to any and all suggestions and advice, also any helpful links to other threads that are year and make specific. MY truck is pretty stock other than the stereo and nerf bars. Right now I'm hoping to get suggestions on the best grill guard options. At this point I'm not sure about a winch but would probably want one in the near future. Mainly it's Headlights, Fog lights, Off-Road lights and Grill Guard. Thanks to all!

 

Headlights are yellowed and irritating. I have done the buffing thing but i'm tired of it. Plus I've seen some online that are pretty good looking, specifically spyder lights. Any suggestions on manufacturers and difficulty of install on the full bumpers? I've seen the led light bars and honestly wasn't even considering it (honestly I still have the "back to the future" blacked out truck image stuck in my head) but I will look into them again, thanks a lot!
