I just want to second or third any suggestions for extra granted maneuver for a crusader build. It's very useful, allowing you to cycle your maneuvers earlier and giving more options when you start a fight. I would also second stone power, it's a really nice feat for a crusader.
I think Nifft's build is pretty good. I personally would prefer Iron Guards Glare or Martial spirit over Bolstering Voice. He's got a pretty good mix of strikes and counters/boosts. One thing to be aware of with a crusdaer is not taking too many strikes. With extra granted maneuver your maneuver pool cycles every 3 rounds, without it's every 4. So it's difficult to use more then 3-4 strikes before you reset your maneuvers. So I would generally try to have 3-4 good strikes, and fill the rest of your maneuvers with boosts and counters. This isnt always easy with a crusader due to limited selections, but it's something to aim for.
Another thing is with a crusader you want to try to use as many of your maneuvers as you can generally. Yes, you do want to use them well, but since it doesnt take an action to refresh and they are going to recycle anyways, you generally want to use them if you can. Hence the reason for not taking to many strikes.
If your just starting with crusader I would say stick with a pure crusader build. It's still very strong, and will allow you to focus on getting the most out of that. Ruby Knight Vindicator is a very powerful build, too powerful IMO, so if you are at all worried about your DM stepping on ToB I would avoid it at first.
