With Human and the Shaky flaw, and the fighter levels, I have a lot of feats at the start.
Dodge, Mobility and Spring Attack all kind of suck, but this is the easiest time to get them, as later in the build a lot of the feats are level specific.
Skill Knowledge (Move Silently), from Unearthed Arcana, isn't strictly necessary, but I found it very useful not to have to plug all my points cross class into both hiding and sneaking to do them well, and you don't get them as class skills until you reach Ruby Knight Vindicator. Another method of getting them as a class skill early is switching fighter levels for Cobra Strike Monk (for which the first 2 level bonus feats are Dodge and Mobility) If you do that wait til levels 4 and 5, and just pump Hide and Move Silently up to 8.
If you plan to take Cobra Strike Monk levels later in the build, you can take Blind Fighting with the early level feats instead of Dodge, Mobility, Spring Attack if you don't like shuffling feats.
If you plan on going RKV but prefer Warblade or Swordsage to Crusader, then you need to Martial Study and Martial Maneuver for Devoted Spirit. I took those at Levels 2 (fighter) and 3.
At Level 6, you can take Fey Heritage, and at Level 9 Fey Legacy. (Thus saving the bother of the good but unnecessary Shadow-Walker template)
I don't like Blind Fight, (Dodge, Mobility and Spring Attack may not be worth whole feats, but at least I use them), so I picked it up at Level 12, and went into Shadow lord at Level 13.
