Sorry for my ignorance, but I'm assuming demosaicing is the process of turning a RAW files data into a viewable image? So, if I did that in DPP, I can't then save those changes in any way in LR? So I have to work on a Tiff?
You are spot on, but Tiff (or jpeg) *is* the way you save those changes for Lr.
Note: you can also accomplish exactly the same thing by exporting an Lr-rendered tiff back to Lr - so choose whichever renderer you prefer.
If you don't mind gigantasaurus tiffs for all your photos, it's actually an effective way to enhance Lr performance, since Lr no longer has to re-render upon each visit to the develop module (somewhat counter-intuitively perhaps, ACR cache is less help than a rendered tiff).
I know some people who do this as a normal part of the workflow: convert everything to tiff right from the get go (after baseline edits applied) - then you don't fret about creating tiffs here and there - they're all tiffs already! (hint: get a big disk drive just for photos, and another for photo backups)
Another option that really makes Lr zip (e.g. order of magnitude faster) is to use a plugin like EditInLightroom - but it puts a hoop in the workflow that you may not want to jump through (works by converting raws to lower-resolution lossy DNG - *much* faster to load for develop, but you can't zoom to true 1:1) - editing such a file however is *otherwise* exactly like editing the raw itself. - changes made to lo-rez version can then be applied to hi-rez copy for export or for 1:1 assessment.
