Newcomer to GetDPI here. But as some of you know I've been around digital IR for a while. Several years ago I was doing IR conversions commercially, but these days I'm happier back concentrating on actually making images.
Here's one of my favourite IR landscapes, taken on a PowerShot Pro1 with 715nm filter:
I'm currently waiting to get my Panasonic G1 back from conversion at Spencer's Camera & Photo with a clear "full spectrum" filter. I'll be using a variety of external filters on it: B+W 486 for "normal" images, and 720nm and 830nm filters for IR. This setup doesn't work for DSLRs, but with EVIL cameras is perfect.
Unfortunately the Lumix 7-14mm doesn't take external filters, but once the camera checks out with the 14-45mm lens I have plans to take on an Olympus 9-18mm (which does take filters).

wrote about this last year.
Using a custom DNG profile in LR/ACR is great for this. But note that most IR shots can use the same WB!
So once you've set the profile in the Camera Calibration tab and chosen an appropriate WB you can save these in a LR Develop Preset and quickly apply them to the relevant shots. In fact, you can save these as part of a new Camera Raw Default for both systems.
This works great if the default applies just to your modified camera (for example if the tuple of model/serial identifies that camera). Unfortunately ACR is not able to detect the serial number of μ4/3 cameras (I don't think they put it into the EXIF at all) and thus if you set a new default for DMC-GF1 it would apply to images from all GF1 cameras (unless the images already had XMP data: it's only used when things are being reset to default).
Where I'm using converted DSLRs where ACR can identify the individual camera this works wonderfully. Import the RAW files, and the hard work is already done! The WB I saved as part of the default is usually fine, although sometimes I will tweak it a bit to suit the way I want to process the image. There's no "additional step in the workflow".
Unfortunately resetting the Camera Raw Default isn't going to work well for my G1, as the filters (and thus appropriate DNG Profile) may differ from shot to shot. I expect to be making big use of LR's Develop Presets...
