As said, the '12SL will have LED headlights and rear exterior lights, but little else. Also as said, don't really expect any range difference by replacing stock bulbs with LED but you might gain brightness or aesthetics but not range.
You got a steal but I wonder whats up with your GOM?? 99 miles is basically unheard of for a 24kwh Leaf, unless someone was coasting down a hill for the last few miles the vehicle was in use on a 100% charged Leaf.....something just doesn't seem right. Oh and speaking of GOM, IMO it's quite inaccurate in the pre '13 Leafs, very optimistic at first and then gets pessimistic towards lower discharge, causing range major anxiety. First thing I'd do is get something like LeafDD(no longer available) or a OBDII adapter and the LeafSpy program. It has a very nice SOC% display among other range indicators, all better than the GOM IMO. With a 11 bar Leaf expect upper 60s to 70 miles for range @ 100% charge, which drops if you like to regularly do 70+ MPH.
If wanting a L2 EVSE(charger) don't waste your money on anything more than 16a @ 240v(well unless you want to futureproof) as 16a is the max you can charge @ 240v, 12a @ 120v.
