another neighbor chiming in...
i think that the space that you've got is going to be tight for everything you want to do there. the card table looks to be a choke point for getting anywhere on that side of your basement. you also need to consider where the PJ is going to live. i also think that your bath is going to be very tight. the shower enclosure's door is either going to open into the WC or swing right across its bow. either way, i would reconsider whether you need that full bath.
i've been too ambitious with my plans and have scaled back several times. a cramped space just isn't very comfortable.
when you pull the permits, be prepared to spend a couple of hours at the county bldg. builders are elbow to elbow in there, however the folks behind the counter are reasonable and took pity on me with there paperwork. you'll need to have a count for all of the plumbing fixture, electrical outlets, circuits and fixtures and you'll also have to draw a sketch of the space on their paperwork. it cost me $250 to pull my permits.
anyway... best of luck to you and please keep the thread updated.
