Yes, your list of files is there.
The Desktop team could provide more details, but it does vary slightly from what I have under mine (we've also changed the default install location with the edventual goal of better separating application vs user data).
Bug 28263 - offline : mac application vs data location & installer privs
Originally drive:\zimbra\zdesktop
Then we started using the %USERPROFILE% environmental variable drive:\Users\username\AppData(hidden folder)\Local\Zimbra\zdesktop\
(or on XP drive:\Documents and Settings\username\Application Data\Zimbra\zdesktop\log)
Did you pick Program Files as the target?
Under my zimbra.webapp:
localstore.jason
override.ini
splash.gif
splash.html
webapp.ini
webapp.
js
& Profiles:
cert8.db
compatibility.ini
compreg.dat
cookies.sqllite
extentions.cache
extensions.ini
extensions.rdf
forumhistory.sqlite
key3.db
localstore.rdf
mimeTypes.rdf

places.sqlite-journal
pluginreg.dat

There's an internal bug open on that actually:
