Welcome to the RS club. Looks like you exhausted your factory options at the dealer but I think you might be mistaken, there is no front TRD sway bar unless you're referring to the strut brace (the one that goes in the engine bay) which is one of the few factory things you didn't get. I love the big brake kit but after getting rid of the TRD's for 18" wheels I like the ride better of them and they can't be run with smaller wheels.
I would say you've got a lot of mods already but there are always more. Headers and S-Pipe are common for people who have modded to the extent you have. Most people opt to go lower than the TRD's will allow. Car audio is a big one as well. I did a rear wiper delete and sharkfin antenna, both were bought from companies that painted them to match the factory paint. I also painted my headunit bezel to match the voodoo blue which was a better look than the black on black.
For your records, Sail Blue by Rust-Oleum is the closed rattle can match to your xB's Voodoo paint.
