Hi

just considering switching to raw with my new G1 X - and then you say convert to tiff

Could you explain why please?

That doesn't make sense. TIFF is just an uncompressed bitmap and so is RAW. The RAW file is just a table of, essentially, voltages from each photosite. When you create a TIFF, the software creates RGB values for each pixel from the voltages of the surrounding photosites. The conversion is not useful because it loses the information from individual photosites. A RAW editor like Lightroom is able to use the information from each photosite, which allows it to correct for things like chromatic aberration.

How about the option for raw +jpg

That doesn't hurt except for taking up more storage space. It's a good practice if you're afraid that you won't be able to process the RAW files into something as good as the jpg the camera makes. Once you're used Lightroom for a while, this fear goes away.
