Re: Total newbie questions about running rigging/sails....

The biggest difference between a jib and a genoa, and which to use, depends on your typical winds. A 150 Genoa is fantastic for winds between 2 and 10 knots, where at higher wind-speeds you'd furl it in to make it smaller. If your winds are consistently below 10 knots, as mine are in San Diego Bay, you'll get the best performance out of a Genoa.
On the other hand, if your winds are consistently over 7 knots, you're probably best off with a hank-on jib. Non-furler jibs point higher (i.e., they can sail closer into the wind) than any furler headsail or over 100% genoa. Furlers are super convenient, but they're not "higher performing" than a hank-on jib by any means. They make for a looser luff, which reduces aerodynamic performance of the sail.
What I do on those rare blustery days in San Diego is cleat off my roller furler at about 90% and then run my Genoa lines inside the shrouds. This gets the Genny in really tight, and it probably performs about 80% as well as a good hank-on jib. The trick is cleating off the roller line tightly so that the genny won't beat out of the furler at all. Then if the winds get really scary, I just keep bringing the Genny in. At one point I had a patch out no bigger than a flag, but it still really helps the helm control to have some headsail out.
If your winds are very inconsistent, as lake sailors often deal with, you might consider doing Highlander's Cutter Rig, where he's put a bow sprit out front and an additional hound atop the mast so he can have a roller furling Genoa 150 and a jib rigged all the time. Then it's just a matter of pulling out one (or both) depending on the sailing conditions. Complicates trailering quite a bit however, so consider your use.
I'm in the process of putting Mike Inmon's roller main reefing system on my boat now. It's $3000 from the factory and I believe it comes with the appropriate mainsail at that price. I bought mine on eBay for a ridiculously low $200 because I was the only bidder. I've got the roller furler on but I have to add some grommets to the sail to modify it for loose-foot usage. I just got the grommeting kit but have yet to modify the sail. I'd like to try to keep the main bolt-roped as well, but we'll see how that works out. In any case, I'm doing this with the stock main which I intend to replace once I've decided whether I'm keeping the roller reefer on or not, so it's my experimentation sail.
I'm considering re-building the Inmon roller furler with a slotted round spar so that I can keep a bolt-roped foot on the main.
The roller furler extends back into the cockpit an additional foot, and it's twice as heavy as a boom alone, so there's definitely more potential for head banging. I'll report on whether I like it better or not.
Sailing downwind with the Genoa to one side and the main to the other is called "Wing on Wing". I find it's much easier than deploying a spinnaker for day sailing. If I were following the trade-winds to Tahiti I'd definitely fly a spinnaker (on a bigger boat).
