I'm one of the god-knows-how-many new guys you're going to run into on the streets this summer on a new bike!
I've never ridden before and have no clue where to start so I'm taking the MSF safety course 5/9th through the 5/14th. After that I'll start shopping for bikes. I do have a few questions and as I said, I'm brand new to bikes so feel free to roll your eyes at my questions...

1) The biggest fear I have is shifting. I've never driven a manual car and realized, motorcycle driving is all about the shifting. Is it easy to learn? I'm concerned about trying to focus on shifting while using the throttle, brakes and turning etc etc... I'm worried my lack of knowledge of shifting might doom me in the course before I even really get started!
2) At 5'8" and about 200lbs is there a bike geared towards my height and weight or am I good to go on pretty much anything? I'm not really interested in sport/street bikes. I think a cruiser would be more up my alley. Something to do the 40 mile round trip to work and back and maybe some comfort cruising on the weekends. I've sat on Harleys Dynas and some Kawasaki mean streaks and was easily able to rock back and forth without worrying about the weight. I know these are very heavy bikes, I just wanted to get a feel for just how big they really are but I'm considering some of the bikes from Triumph and Ridley automatics.
3) Is there a specific manufacturer of bikes, helmets, equipment I should avoid at all costs for whatever reason?
4) If someone could type a basic guide to shifting, I'd appreciate the hell out of it...
Any other do's and dont's or general advice to a newbie would be great. And I'm one who'll actually listen. I have no intention of dying or paralyzing myself so rest assured I'll read and take to heart what you write.
Thanks in advance to anyone who takes the time to answer....
