If you're wondering about character creation, check out the current campaign info: Solace: Collapse for the "getting started" guide, and an introduction.
Character Sheet
You can grab the PDF for the Fifth edition character sheet here: 5e Character Sheet, and a number of "alternate" versions are listed there as well.
Rule Books
Here's a link to a PDF of the Player's Handbook: [Dropbox Link] (this is my own PDF I'm sharing on dropbox for all of you)
Or you can buy it on Amazon: [Amazon Link]
and the Wizards of the Coast website for it: [Wizards Link]
You can also find the "Basic Rules" here: [Basic Rules]
Quick Web Reference
There is a wonderful online resource that basically collected all of the stat and numbers based information and put it together in a multi level database.
Basically, you can search for quick reference stuff there.
Other Player Resources
Here's a bunch of player aids available from galeforcenine, I highly recommend them as a store, but feel free to look elsewhere.
I haven't messed around with the spell decks and other aids, but I plan on doing so sometime soon:
