Buy what you'll wear.
As for riding shoes, they sort of work. I have both full boots and riding shoes. Depends on the off bike activities. Just like normal clothes. You don't wear flip flops into a boardroom and you don't wear a tux to mcdonalds. No one set of gear will fit all situations. To get started though, I'd go with Riding shoes as you'll always find a use for them. Make sure you do not get waterproof. As good of an idea as that sounds like, nothing is more disgusting than wrapping your feet in a plastic bag at 40 degree weather with no ventilation.
Riding Jeans are like riding shoes. Good enough till they aren't. Get something that will be good for off the bike. Try not to overspend, but sadly, the breathable, comfortable and protective riding jeans are all pricy. If you were cash constrained, pants are maybe one of the last pieces.
Back insert pockets are typically proprietary shaped. I'm not sure about your super speed jacket. Get something but don't go crazy. CE1 rated armor made of something like D3O will be your best bet if it fits. If you want more, a CE2 protector will add a lot of bulk so if you are going to a retailer, see if you can try it in your jacket.
You didn't mention gloves. Please wear gloves, proper gloves.
If you find that riding agrees with you, then wait till the motorcycle show in January. GP Bikes has historically had signficant discounts. You'll have had more saddle time and you'll start to get a sense of what kind of rider you are. As it stands now, there's no telling if you are a custom Dianese track racer, a Joe Rocket commuter, a FOX single tracker or a muscle shirt stunter.
