You can follow the progress of rumors about clubs on PI reopening on my Blog located at:

There is a lot of mention about Jellyrolls in this thread but no mention of Atlantic Dance Hall which is right next to JR's. Admission is free and you can dance all you want and the DJ will play your requests if he/she has it.
Pleasure Island is not a place to plan on partying. Paradiso 37 is mainly a restaurant although there is a tequila bar in there too. Raglan Road too is mainly a restaurant and you'll find it clears out after 10pm. That leave House of Blues but HOB is a club that depends on whether anyone is performing as to whether it stays open late. If no one is performing then the dance club part is closed. Check:
www.houseofblues.com/orlando Service Industry Night every Sunday night is packed to the rafters though.
Do plan to visit CityWalk if you can because it's as close to the PI experience as you can get. You can get a pass into all the clubs for $11.99 which is about half of what PI used to charge. Stick with Th-F-Sa nights as the rest of the week is dead.
