Not yet, but we will setup a mailinglist if there is popular demand for it.

If you want to generate files for the MapnikRenderer plugin you have
to setup a functional postgis database. Nevertheless, if you just want
to use the OSMRenderer plugin, which fetches tiles from the
OpenStreetMap server, or use provided data packages no database is
needed.

MoNav uses Qt for:
 - GUI
 - file access / memory mapped files
 - accessing GPS hardware
 - timers
 - strings / UTF-8 encoding / decoding
 - debug output
While porting the plugins to a different toolkit is not be much work
due to sparse Qt usage, the GUI would have to be rewritten completely.
I have heard that Qt might work on Android, though, and would advise
to pursue that.

The main trie file containing all place name should be around 3MB, the
sub-trie file containing all the street name tries about 37MB and the
way data file about 70MB. While the main trie file should always be
the same size, the sub-trie file depends on the type of streets you
are routing on. Only routeable streets are imported into the address
lookup.
If your files are a lot smaller than the data packages offered the
importing seems to be at fault. Have you setup a correct speed profile
or used the default one? Have you selected an appropriate vehicle
type? Is your osm file compressed as bz2 or uncompressed?
