Dude, I don't know why, but whenever I read about people getting into melee, most people start playing Marth and are then drawn to Falco after some period of time.
That happened to me, I play as both Marth and Falco, too.
Anyway just play, play, play as much as you can. practice your tech if you can't play anyone. Check out the boards here for character specific stuff, check out the character guides. Watch videos. Have fun.
I'm sorry I can't be too much help, I'm a noob myself, I've only been playing a couple months but I would say I'm definitely better than I was when I started.
I'm also waiting to attend a local, just waiting for the right time I guess. I'm glad to know I have a pretty poppin scene where I live.
Anyway just play as much as possible, have fun, and just check out the guides for Falco and Marth to get started.
You'll be better in no time.
