I'll add a little...
When I turned 16 my Dad made me learn to drive his 1978, three-speed in the column, Long-bed, Chevy Pick-up truck. He said, "If you can drive this, you can drive almost any vehicle on the road." I did and he was right. This applies to guitar, too. An acoustic is a lot harder on the fingers than an electric, but you gain strength by playing one. You might try having the string height adjusted professionally to lower the "action".
As for finding the right chords, just don't be afraid to learn new "shapes". I have a "C" that I learned from playing "Every Rose Has It's Thorn" by Poison when I was a kid. It's 3 3 0 2 3 x (from high "E" to low "E"). My buddy and I have called it the "Poison 'C'" since then. Sounds wonderful and I use it often instead of a regular "C", but I never see it called for in chord charts of songs. In other words, you'll develop you're favorite ways to play a chord over time depending on what sounds good to you.
Lastly, if you love playing, you'll constantly discover new chords and new ways of forming them. I recently learned "Alone Again (Naturally)" by Gilbert O'Sullivan (or Raymond O'Sullivan) and THAT song has some unique chords that I have never played. But, I have since used some of them in songs I have written. It's like anything else in life, if you are a true student, you will never stop learning.
