Don't waste your time hunting down those - you don't need a dat file for rebuilding/scanning/fixing ROMs (*).
Just point the clrmame Profiler to the mame executable of the version you want to scan, clrmame reads all the info it needs from that.

While it does that, a couple of dialog boxes will pop up, just click yes on all of them. Except if clrmame asks you about importing software lists, then you should click no for now, unless you know what that means.

Well yes, you need the missing files, there's no way around it. Clrmame will only work with the files that you make available to it. If you're still missing files it will go as far as it can with what you have but of course you'll still be missing files.
That should be obvious. For the same reason, you can't play a game that you bought on Steam until it has finished downloading.

Use the "add path" function from the settings menu. Set an "add" folder, and leave all the new files zipped in that folder. You asked about this - in the Scanner, click the button labeled "Avail. Sets". This way clrmame will only rebuild the ROMs you already have in your MAME roms folder and not add new ones, even if it finds them in your "add" folder.

Then start the scan and just click yes to everything.

(*) I think for really really ancient versions of MAME you might need a .dat file. I don't know how far back you have to go. Anyway I'm sure clrmame will let you know.
