Read the documentation and follow tutorials.
The quick way:
- profiler (->create): setup mame as your data source
- settings: setup rompaths
- scanner: hit scan, let cmpro fix (when options are enabled) all issues.

After that you should only have missing files (or not-fixable issues). Add new files by using fix-missing or the rebuilder (or even rebuilder functionality via drag'n drop in the scanresults tree window).

You don't have to unzip anything. Either you use fix missing, then it picks up roms from a setup add-path or you drag'n drop them or use a rebuilder source.

Again...read the docs/tutorial
