Welcome to EVOtuners!
You have some nice, simple stg1 mods that are very useful on a IX. The only thing I wish you hadn't have gotten is the Clutchmasters clutch, but oh well. Hopefully, it will work well for you.
You're not missing anything, imo, but you should not have colder plugs. You should be using NGK BPR7ES (stock heat range) unless you run into problems with boost breaking up. If you are using NGK BPR8ES (1 range colder), then they should still work, but they will foul out sooner, because they work best when you're boosting hard. When you're cruising, they will wear out quickly.
