Without full casting, you'll probably have to rely on magic items to get around some basic caster tricks. Have at least one rod of cancellation, some item that grants a fly speed (or better yet, some racial [Ex] ability, for instance if you're a Raptoran), the maneuvers that swap saves with concentration checks paired with a Third Eye Concentrate, and maybe a dip in Swordsage to get some mobility powers.

Factotum is wonderful, but despite its love on these forums I wouldn't pump Font of Inspiration. Unlike a caster, extra actions aren't the end-all to winning a combat; you're going to need to increase the effectiveness and availability of your actions with your available feats instead. Different ways to go include the mage slayer line, power attack optimizing, reach lockdown, stormguard warrior, [strategies I missed], or some combination of the above.

In general, think of every clean trick a caster could pull, and try to find an item or an ability you can grab to get around it. If you have your bases covered, and you actually get to an opponent and start attacking, you should be able to either down them or seriously cripple them with strikes + extra actions from cunning surge.
