Nine people to start, better than I hoped for. Well I can adjust traps and monster counts for 9 players. That wouldn't be hard. And could let me throw more... interesting things at you guys.
Regarding Character level, we would be starting at level 5. This would give you your initial archetype, and the ability to multiclass if you wanted.
Starting stats are the same for every character, however these are before racial bonuses: 15, 14, 13, 12, 10, 8. So everyone gets something they're good at and something they're not so good at. However, I am allowing Human characters to use the Variant rule for Humans.
Everyone will get initial starting equipment dictated by their first class. 1 Rare magic item, 2 Uncommon magic items, and 5,000 gold pieces to spend on anything else you want, including upgrading equipment and so on.
IF you have the stats and everything you need for your characters great. If you don't have the books or rules or really anything else then here's something Wizards of the Coast put up on their website for free http://media.wizards.com/downloads/dnd/DnDBasicRules.pdf
It's only the basic rules, nothing all that great, but they do have the basics for classes, some of the more popular races, and such.
