The Burning Brand boost from Desert Wind increases your reach by 5 ft.
Also, replace levels of Samurai with levels of Warblade. Same fluff, better mechanics.
DO this.
The problem with Thicket of Blades is you need to either be a level 5 Crusader to get the Stance (which is an amazing Stance, by the way, you are right in taking interest in it), or take the Martial Stance feat. Since Martial Stance feat requires you to first take Martial Study feat, and since Thicket of Blades requires you to know one Devoted Spirit Maneuver to qualify, consider Crusader's Strike, Vanguard Strike or Foe Hammer. You'll need to be a level 10 non-Crusader to qualify to take the Martial Maneuver feat for Thicket of Blades. Take this into consideration when designing your build.
