i started with a nylon classic but found i needed to switch to a metal string acoustic to get used to a smaller neck. it was horrible at first but over time i am getting better.
first thing i did was learn simple pluck like mary had a little lamb and twinkle twinkle in single voice. from there i worked on zombie from the cranberries (to give me something i could hear..so to speak) but sadly it does take time, i'am still struggling with strum patterns and picking rhythms.
as wingman23 and Slipin Lizard has said take your time to get all the strings clear on pluck. (oh and i found cutting my nails right down helps alot).
PS personally i wouldn't worry about bar chords yet, they can be hard on the hand.
