Thanks for the complement - I'm glad you're digging it. I absolutely love IR. I'm shooting with a KolariVision 720nm converted D7000 but am seriously considering converting my D800 (which is largely gathering dust and losing value on the used market) to 590nm with the idea that I can get additional filters to go to longer wavelengths. The only thing is I'm hearing that it's almost impossible to get an in-camera WB on the D800, so I may just wait (I also had a brief exchange with Nasim Mansurov about his converted D800 and he said that if he had it to do again he wouldn't have converted a full frame camera, but I couldn't get him to elaborate. So in the meantime I'll keep shooting with this one.
As for P&S cameras, I'm assuming none of the ones listed shoot RAW, so you'll be dealing with JPEG files, which is great provided you can get the camera to white balance properly (I believe most will). After that it's all a matter of playing in Photoshop. Most folks do traditional Red/Blue channel swapping. Sometimes I do, sometimes I don't, depends on the photo and my mood. I've been playing a lot w/ B&W lately, particularly on bright days with nice clouds - you can really get a sky to go dark in post.
Kolari has some good, basic tutorials and PS Actions that you can download on their website, including some that will supposedly approximate other filter output from the 590nm. I haven't mess with them.
One thing for folks doing DSLR's, make sure you send a lens in for focus calibration with the conversion. Also, some lenses are more prone to hot spots than others, so check their database as well (the Sigma 10-20mm would be a perfect IR lens but it has hot spots off the charts).
