Welcome, jaxxQ.
Whatever you decide, you are going to love cooking on the KK. While your previous ceramic experience will come in handy, cooking on a KK is not like cooking on any other ceramic; but, the good news is that it's actually easier once you get the hang of it (vent settings, which grate level works best for which foods, direct/indirect). The Forum is a virtual encyclopedia of helpful posts that are easily searchable, OR be lazy like most of us and just ask - we'll be more than happy to answer any questions or give advice (even if unsolicited - LOL!) Like this one - based upon what you've posted, I think that you'll be happiest with a 23"/19" combo setup, rather than the solo BB 32.
