Some good conversation here!
I would totally rock a PG t-shirt, hoodie or hat.
I don't really foresee the Shop as being too heavy on micro-transactions. They want to keep it fairly simple - A few package deals to choose from, maybe a few single-line items like order a custom title or the custom gravestone thing, maybe some simple services like guild rename and such. T-shirts and items of that nature are possible but we'll have to look into costs and logistics for it first.
The VIP tokens for the VIP subscription option will also be sold there as well. To set expectations for that, The VIP option is very likely not going to come into play until right before release.
I gotta admit I'm surprised I have not seen more chatter about custom titles on this thread so far. So I guess I'll poke your brains about it. How do you feel about that? Non-bestowable vs. bestowable?
And finally to clarify on one point:

Extra accounts will not be "outlawed", you just won't be able to log them all in at the same time. You can own as many accounts as you wish, but you will only be able to have one logged in at a time. Also to be clear, that will not happen until there is some form of item mail in place.
