Tell me how... to phase out a nap

Alright friends, I could use some advice.  My struggles with Jordan being a terrible sleeper are well documented, thanks to me ranting on facebook.  But... now we've got another problem.  Spencer turned 3 in April and he's decided he's done with naptime.  It really depresses me, but at 3, I guess he's lasted longer than some.  But... he's turned into an afternoon NIGHTMARE.  He throws tantrums (which is unusual for him).  Cries like a diva (also unusual).  Turns into a bully with Jordan and is intentionally mean to him (and he's normally so sweet with Jordan).  By 4:00-5:00, I'm so done and ready to put him in his bed and leave him there.

Now... I'm sure I'm not the only parent to have gone thru this.  I remember the transition from 2 naps to 1 was fairly rough for a while.  So it only makes sense the transition from 1 to 0 would be rough too... but jeez.  Did I mention he's a nightmare?  By 7:00, he's usually thrown into bed 'cause I can't take it anymore.  And neither can Jordan.  There's only so many times Jordan can take golf ball thrown at his forehead from only 1 foot away before he's gonna have problems.

So... how do I transition Spencer from 1 nap to none?  Keep putting him to bed earlier than normal until he levels out a bit?  Keep early bedtime forever?  (ha, part of me would love kids bedtime at 7:00, but it's kind of impractical if you ever want to do anything)  Make bedtime early for a few weeks and then slowly move the time back to normal bedtime (which was 8:00-8:30)?  Maybe just sell him?  (I'm kidding... kinda)

And what do I do with him now that he doesn't nap?  I need that time in the afternoon when they were both asleep to accomplish stuff.  Household stuff.  Work from home stuff.  Sometimes just catch up on a 45 minute show (pretty soon my DVR is gonna stop recording stuff cause it's so full).  I know it may sound selfish to some, but I miss that small break I used to have in the afternoons.  It *almost* kept me sane.  Now Spencer's always there.  And before you suggest that I make him play quietly in his room... he and Jordan share a room, so he can't play quietly in there since Jordan is in there napping.  So he's in the living room with me, begging me to play with him (even though I spent all morning when Jordan was napping playing with him).

If you've got any advice, anything that worked for you, please share.  I'm desperate :)
