I'd add to the general comments:
I have a new-to-tabletop-gaming player in my campaign. She's playing a human sorcerer. She loves it.
She's a long way away from "optimized" and doesn't tend to focus on the forums, but she picked it up right away and she loves the sorcerer's flexibility, basically being able to scorch anything that comes to close to her (with a lot of close burst and close blast fire powers) or just rain thunder and lightning down on them from range.
So, for cutting through the "overwhelm", that's what I'd recommend.
Besides the great advice to run the Character Builder trial to make your characters 1st, 2nd, and 3rd levels, and plunk down the $ if you're getting value ..
.. I'd say the other piece is "get a more experienced player to sit with you while you do it", they'll be able to explain the costs and benefits of certain powers or choices quite well.
Remember, you aren't locked into any of your choices: each time you level up, you can retrain one thing about your character that you don't like. Took the power "Utterly Useless"?
Fine, once you've figured out that its utterly useless, you level up, and you retrain it to "Looks Much Better"!
She's certainly done that with one - she's playing a Chaos Sorcerer (Wild Magic), and hadn't quite figured out how useful the Level 2 Utility power that lets her choose whether her attack die roll was even or odd was. As she saw how many powers relied on that, she decided to retrain to learn that L2 Utility power.
