Hey Don
As slothy said, you'll want side opening bags, if you plan on going with a larger Tour Pak.
My Champion Sidecars trunk was smaller, and my rear opening bags would open just enough to get into. (edit- see you are doing without the trunk.)
As GrinderEFFE said the Venture and Tour deluxe bags are the same from about 99-10.
The early model Tour Deluxe bags(97-98 ??) were slightly different though. They had latches on the front and rear both, and lids would remove completely. I really like the looks of them, no hinge on the side.
Think VegasDave here has them on his..
As far as fairings, there are so many to choose from now, and most of them are pretty good quality.
Main considerations are if you want a two piece, with inner and outer (easier to get to electrics), or a one piece (probably little more weather resistant). Also, do you prefer ABS or fiberglass. Oh, and of course price.
Most fairings I've seen will stand up a little straighter. A WOC fairing, which is what I have, will lean back more. Although my WOC leans back a little more, which I like the looks of better, the windshield leans back more also, and it takes a taller shield to get the same amount of wind protection as the more upright fairings with a shorter shield.
My shorter shield gets used most of the time, and looks a lot cooler, but my taller shield gets used when weather gets a little cooler..
