Oooh! Evil Knight! You'll want to multiclass a bit - 2 levels of Fighter for the feats, and 2-3 levels of Monk for the saves and abilities. How far are you going to take the class? Are you heading for Blackguard?
For stat arrangement, try Str 15 Int 11 Wis 9 Dex 13 Con 18 Cha 14. At 4th level you'll improve Str to 16.
If you go Dwarf instead of human you'll be Str 15 Int 11 Wis 9 Dex 13 Con 20 Cha 12.
At 3rd level, you'll be Ftr 2 / Kt 1 - BAB +3, HP 36 F/R/W 7/1/2. 4th level will see you Ftr 2 / Kt 2
At 8th level, you should consider being Ftr 2 / Kt 4 / Mk 2 for BAB +7/+2, HP 86 F/R/W 11/5/6. And in Mithril half-plate so you can still use the Monk's Evasion ability. I'd suggest levels 7 and 8 as your Monk levels so you don't lose that second attack.
If you don't go Prestige, Ftr 2 / Mk2 / Kt 16 is well nasty.
