I played bass and keyboards for a while and returned to 6 strings about 1 1/2 years ago myself. While my playing isn't anything of greatness, I've learned a huge amount and the improvement is welcome. Trust me, if
I can learn guitar in my mid 40's, anyone can! Keep it fun, and the rest will follow.
The learning curve can be improved upon by online lessons, like from a few members here: DolphinStreet.com (Robert Renman)

and Mark Wein

Also a few youtube teachers, like Pebber Brown
http://www.youtube.com/user/pebberbrown, or
http://www.steviesnacks.com/, plus so many more out there.
Also, the Fret Logic III books/DVD by Bill Edwards is a good learning ground for the CAGED chord shape stuff.
I enjoy playing along with backing tracks to improve creativity and chops, like at
