I used mostly Blue sea gear as well. For wire to wire joins I soldered and used a silicone grease that a mate from work recommended (can't remember the name of it now) and then shrink wrapped. For joining wires to bus bars etc I just use eye terminals in the correct size for the wire and use an proper crimping tool, I have had to many problems with soldering terminals in the past and only crimp now, much easier to repair or fix on the water if something does go wrong which is vary rare.
The only other thing I can recommend is to forget about using ply if you are doing the decks and get a product called nema board. I used this on my casting deck 3 years ago when I did the electrics and it has held up fine. It was about twice the cost of ply but I figured it was worth it as I would never have to replace it again ( except when you buy another project boat). I was going to do the rest of the deck in it but sold the boat instead.
One other thing is to look out for galvanic corrosion on Quintrex's, not sure if it is the same on other painted aluminium boats, as I took out every screw in the boat when I got it and replaced them along with a good amount of duralac. It seemed to slow it down, it may also have been due to the negs being connected to the hull.
Anyway take your time and don't be in a rush to get it on the water. Sometimes fixing up the boat can be almost as good as going fishing. Did I just say that? I think I need another beer.
