My suggestion would be to stick with 2-3 chosen creatures instead of going all over the place with them. You don't really need Progenitus AND Emrakul, Magister Sphinx isn't all that great, etc... The rest of your deck should be filled with either card draw, mana acceleration or control. Magma Jet would be great, if you want to stick to mono-red, Browbeat isn't too bad...

Check out my Myr deck for ideas: http://www.mtgvault.com/ViewDeck.aspx?DeckID=191167 It might not look like much, but trust me when i say it's just balls-to-the-wall insane.
Oh, Terra Eternal might be a good idea.
All three "commands" in your Commander's colours.
I'd go for 37 lands, that's what i run in my EDH decks and even then i sometimes end up mana-screwed early game lol. but yeahj, 35-37 should be good.
