New member with a lot of questions

Hey Guys, I am a new member and just purchased (with my fiancé) a 2016 trail 4runner in charcoal. I have a multitude of questions about different mods and what is good and bad.
I am looking for any advice or recommendations from all of you who are way more experienced than I at this. The first mod im looking at is adding a light bar into the front grill, I'm doing everything clean and sleek for this truck. I am looking at adding an optima gel cell battery for a little better power output for the light bar, and future add additions. Is there anything better out there now than the optima's? I have used them in the past on my f150 for wheeling and have good luck with them.
I was also wondering if anyone had recommendations on light bar brands, I am unfamiliar with most and have been doing the research and most seem ok.

Thanks for the patience and Help!

 

Light bars, I can say the the following are pricey but quality:

Rigid
Baja Designs
Cali Raised

Optima are great batteries, perhaps a bigger alternator?

As far as mods you need to decide what function your truck will be.

Ours is our road trip + Camping vehicle, so mods are mostly around comfort with a little armor for occasion exploring.

The Tacoma is more for harder wheeling.
