Rapidstrike, which someone else mentioned, can be found online. It's a crucial part of the hard-core King of Smack build, but it's not available to you by Level 10 anyway. Still, it might be worth asking your DM if he will allow it in the future, because that will affect your choice of Race. If you are heading for Rapidstrike, you will need to be an aberration or dragon. (The Elan race from the Expanded Psionics Handbook, LA +0, is recommended.)

But yeah, basically, what Person_Man said. Knockdown is optional (but nifty). Robilar's Gambit is another goal to get eventually, if the DM will allow it.
