First, congrats on getting a free exhaust. That's awesome.
Secondly, after the CBE is added, the majority of the gains are realized. Seems like adding high flow cats will only net you an additional 5hp or so.
So, if it's between the two (intake or cats) I'd go intake. Plus, there is always emissions, visual inspections and CEL's to worry about with high flow cats (not a big deal, but I factor it in).
But, either way, stay clear of changing the headers. Doesn't add much of anything.
As for tuning, you're good for now. But, if you add the intake and high flow cats, you'll want to get a tune to correct the A/F ratio. You can go uprev or AAM.
