[Dx4win] LoTW problems

[Rick Murphy K1MU]

OK, I'm kinda confused about what to do when importing from LoTW.

I've uploaded my log from 6.02, so what I need to do now is two things:
1. Mark the QSOs in my current log as uploaded.
2. Download from LoTW so the confirmations there are marked properly.

The help file is less than helpful. There's no "LoTW" in the index, and 
the "Export for LOTW" topic starts with

Export all QSOs marked for upload to an ADIF file. The ADIF file

i.e. it ends in the middle of a sentence.

For download, do I generate an ADIF report from LoTW for just QSLs, or 
for all QSOs?
Do I import this using an ADIF import, into my current log?

How do I mark what I've already uploaded so they don't get uploaded again?
