Import & Library handling Question!

Question

Is it possible to do the following 100% successfully?:
1. Import images from CF card into LR
2. cull in another program
3. create a new folder on hard drive &  move all RAWs to be edited into this new folder
4. Import the choosen images to be edited into LR -  from this new folder created on the hard drive (without them being linked ot the original import library when they were uploaded from the CF card)
5. send them out as small DNGs to editor
6. then receive the XMP files back in LR to update the RAWs with edits by dropping the XMPs ito the new folder that was created for images to be edited and let the RAWs update
7. save the updated RAWs that now have the edits applied from XMPs somehow (in RAW format still)
8. move onto Photoshop (ACR) to do any last touch-ups of my own, save as JPG, submit to client. 
Thank you in advance!!!

Answer 1

As I said, there is no such thing as "small DNGs", maybe they mean "Lossy DNGs"? Perhaps you ought to confirm that's what they mean.
They edit my images and return them as XMP files.
Well, that's interesting. Lightroom offers no way to create XMP files from editing DNG files. Perhaps they have a plug-in or other way to do so. Technical correction ... they don't return the images as XMP files, they return the edits as XMP files
They instructed me to drag and drop the XMPs into the file folder that the RAW images are in and watch them update in LR.
This doesn't happen by itself. You would have to go into Lightroom, select the desired RAW files, and then issue the command Metadata->Read Metadata from Files
Once they are updated, they can get converted to JPG for client
Once they are updated, you can Export them as a JPG
What I want to know is, if I were to use LR to import and rename my files for me, save to one file folder on hard drive. Then cull the images manually, and create a "to be edited" fil folder - drag and drop the RAWs into that file folder.  Can I re-import the files into LR from that new folder?  ***Will LR recognize them as previously imported images linked to the orginal uploaded library, OR will LR link these reimported images to the "to be edited" folder that I created????
You are creating extra work for yourself. The idea of moving photos to a specific folder and reimporting is completely unnecessary here. Once they are in Lightroom, select the desired photos, assign a piece of metadata to those photos you want (color label, flag, keyword or whatever), and export as DNG for your editing service. No need to move the photos, and no need re-import. This takes you much less time than creating a new folder, moving the photos and reimporting.
Why are you even using Lightroom here, as you don't seem to need any of Lightroom's features. Why not use Bridge/ACR?
