I'd go for a more focused and faster Land destruction build:
4 Birds of Paradise
4 Blastoderm
3 Flowstone Overseer
4 Stone Rain
4 Pillage
4 Creeping Mold
4 Tectonic Break
4 Shock
3 Hammer of Bogardan
4 Karpulsian Forest
4 City of Brass
4 Rishadan Port
5 Forest
9 Mountian
SB
4 Reverent Silence (maybe even more enchantment control will be necessary)
1 Uktabi Orangutan (Diamonds, Cameos, Idols)
4 Flowstone Wall (Blastoderms, Kavu Titan, etc)
2 Flowstone Slide (anti Rebels/combo's very well w/Derm)
4 Boil
However, I think Gizmo's suggestion of running Mono-Red with R/G lands for SB options is probably the best way to run any Red decks right now.
4 Stone Rain
4 Pillage
4 Tectonic Break
2 Kris Mage
4 Rogue Kavu
3 Flowstone Overseer
4 Seal of Fire
3 Hammer of Bogardan
4 Mages Contest
4 Fire Diamond
4 Rishadan Port
4 Dust Bowl
4 Karpulsian Forest
2 City of Brass
10 Mountian
SB
4 Boil
3 Flashfires
4 Tranquility
other stuff as the metagame dictates
I would be tempted to add Seismic Mage and Squee, but the deck need survivable offence. Squee adds excellent Blastoderm defence, however. Lots of questions, too little information to be certian.
