This is a stronger spec than the one you're currently using. Improved Disciplines, Improved Disarm, Puncture, and Safeguard are all relatively weak PVE talents.
As far as your gear goes, don't worry about it too much. Keep it up to date and realize that in many cases greens (of the Champion/Beast/Soldier/Bear) may be stronger than outdated blues. Don't kill yourself for gear - just level through Outlands as quickly as you can and get into Northrend with a solid mix of blues and greens.
