I totally agree with you here.
<<Disclaimer - the following represents my personal opinion>>
I personally would not recommend ANY carbon on a commuter bike unless you meet any or all of these criteria:
- you ride for a sponsored team who can replace stuff for you and pay for medical costs resulting from failures
- you weigh 160 pounds or less and use your commute to train for racing
- you are an elite level athelete who needs any 'edge' you can get (use of carbon is still debatable, even here)
- your only bike is/has carbon and you can't muster the cash to buy/build a commuter.
- the carbon in question is non-structural (derailleur plates, brake levers) and just happens to be a feature of the component (i.e. you didn't have a choice to opt out of it).

This, of course, that's just my opinion, but I'm a pragmatic, ex-racer, retro-grouch and feel that (above conditions excepted) carbon is way over-rated, dangerous and unnecessary. It is also worth noting that I'm a hair over 6'2 and my 'prime fitness' level puts me at about 185 lbs, so structural carbon is marginal at best for someone like me, and I've seen too many carbon failures over the years to have any trust whatsoever in the stuff. <<rant over>>

With that editorial out of the way, and back in to the spirit of the post - welcome back!

for glasses, I use yellow-lens Rudy Projects, which I like because I can use them in all lighting sitations. In order to avoid pressure points, I put the glasses on AFTER buckling my helmet so the earpieces are unobstructed.

Handlebar-wise, randonneur or 'ergo bend' bars might suit you, as they offer a number of comfy hand positions.
