I would agree with Graham that you need to check out airheads.org. But, here a a few thoughts...
For commuting, I would look for a real, full fairing like Like this Windjammer
You will have as much protection from the weather as you have on your LT!
Next, the bags you want (traditionally speaking are Krausers
here is a pair on a nice R100S.
That's the fun stuff, now the downside. Airheads are OLD fashioned bikes, and this is the 21st Century. I love my R100/7 on empty country roads with no traffic. I hate it in town. Or, on a busy expressway during commuting hours. One of the BIG drawbacks is brakes. They suck. Ride your LT and do a few stops, like in rush-hour, then do the same thing on the R90. The difference is enormous. And, no ABS!
Also for commuting, the lights, front AND rear are poor. Tiny taillight, tiny directionals and a weak headlight. Not my first choice for being seen.
Save it for weekends in those beautiful NJ hills and valleys of yours!
Sorry to be a wet blanket. Just my $0.02.
