I'm looking for any advice at all on my loadout, particularly the shields and what kind of protection (if any) I can expect from them. Thanks.

I went all class A modules, class A3 fuel scoop, 64 cargo, 6 gimbaled multi cannons, adv and detail scanner, 2 point defense front and rear, chaff and ecm, mil grade armor. Can still jump 25 ly mt. leaves me room to add a refinery mebbee at times and a auto repair unit. Haven't decided yet.![]()
If you're headed to deep space you really don't need anything except the A3 shield (and maybe an A2 shield cell). Some people even run completely without shields to maximize jump range.
There are no NPCs once you get 50 LYs away from settled space.
Here's my exploration ASP:

Well yes that is true, deep space exploration does not need shields. It is going out and coming back in that *could* be problematic without them. For the extra couple of LY you can get in a jump by dropping shields / power supply down, I don't personally believe the risk greater than the reward. How harsh would it be to come back from a week long trip, only to be interdicted and destroyed by an NPC a few LY away from your dock. The peace of mind the shields give me is worth much more than 2 LY jump range.
The fuel scoop is overkill. I am running a B3 scoop, and it is a bit on the low side, but not by much. A3 should do.
I run D modules for everything except FSD.
For shields I have a D5. Wouldn't like to run without (imagine meeting that alien civilization and being shreddered by the 1st ship you come across.
If going for long range I'd update life support to A. Repair unit... does not seem worth it. Might come in handy if you suffer failed thrusters or FSD... the chances for that, however, are fairly slim.
Agree with you on the repair module, it's gone.
I don't see any reason to downgrade the fuel scoop. A class 6 shield generator is too heavy and the only other options for that slot are repair modules, shield cells and cargo racks. Please correct me if I'm missing something.
Life support is downgraded because I'm not going to be within 25 minutes of any stations.
The only negative about the scoop is its power draw. Compare it with a class 3 (you'll have to observe your ship stats in the outfitting panel since the item description doesn't tell you power consumption). If it's enough to be able to downgrade your power plant to a D or even to a smaller class (thereby saving weight and increasing jump range) its worth doing.
If it doesn't make enough difference to affect your reactor slot then yeah, leave it.
