What level are you starting at? At high levels, if you intend to use force powers offensively at all, you need the Fringe Savant + Serenity (+ Baran Do) combo. Dark Rage + MSotF + assorted stuff will get you plenty of murderation (although you do need force point regeneration, at least 1/encounter), and it doesn't require Serenity spam. I'm partial to unarmed combat myself, but anything melee works.
Dipping 3 levels of Scout is basically mandatory for all Force users (Fringe Savant + Evasion), just like Noble 1 is basically required for Droids.
Honestly, deflect/block seem like losing options at high levels. Thanks to the skill vs. attack/defense scaling issues, there's basically no way to reliably deflect at high levels outside of Serenity, which is not at all practical, or possibly Crime Lord. You're much better off optimizing initiative and playing RLT with force powers at that point.
That said, can you be a "shady" Jedi? Because Crime Lord rocks for defensive builds thanks to their fear talent. -6 to all attacks made against you is really solid. It's one of the few ways to get deflect to actually work decently at high levels.
