I think he meant the pounce ability of a level 1 Lion Totem Barbarian. Is it not called Lion's Pounce?
I agree with Kat's feat choices. I'd recommend after getting a total of 8 HD and class levels to dip Warblade 1 or Crusader 1 (I'd go Warblade, especially if you're new to Tome of Battle). Grab stance: Leading the Charge and maneuvers: WR Tactics, Battle Leader's Charge, and some other maneuver.
(My advice: pick Disarming Strike or Wall of Blades from IH and spend your 9th level feat to pick up IH Surge, which requires already knowing an IH maneuver. It's a lifesaver, especially if you later go into Frenzied Berserker. Alternatively, pick either of those first two and get an IH vest for 3000 gp to use IH Surge once/battle anyway.)
With Knockback, you'll want ot pick up Improved Bull Rush (if it's not required for Knockback anyway) and Storm Trooper (trading AC for Power Attack instead of attack bonus + knocking said foe back 20 ft afterwards = win. Note using this, Wall of Blades becomes very handy, too.)
Optional icing: Combat Brute tactical feat, Cometary Collision (+ Steadfast Boots from MIC). Former lets you do scary PA damage the round after charging, in case you failed to knockback the foe, somewhat synergizing with Shock Trooper. The latter, with boots, means you can ready to charge as a standard action at any foe that charges into or past your charge range, AND do double damage with any weapon since you readied against a charge!
