Necessary electrical upgrades?

Good Morning,
I've added a Warn winch and a cali raised light bar, which has a relay included, all my electric in clean and tight. I'm now adding 2 sets of BD squadron lights, which do not include relays.

I was planning on wiring direct to battery using the included inline fuses and rocker switches BD included, these lights are 2 amps a set. Should I be upgrading with a fuse block and main circuit breaker now, to tie everything into and should I be adding 2relays for the BD light set? I'm not planning on adding anymore electric add ons, except to replace my battery to the series 27 in the future.
I've all ready read thru the threads on fuse blocks and electricial issues.
What I need is recommendations for a basic, clean system for a gen 3 Tacoma TRD OR w/auto.
Your recommendation would be helpful.
Thanks and God Bless.

 

I put a quick disconnect switch between my battery and winch. Blue Seas diesel; good for 600 amps cont. I then take the Aux off a 30 amp fuse and sub divide to the individual device fuses (5-10 amps) off the 30 amp.
