If I understood you correctly I have done everything right without even
knowing about the possible technical traps? I do not need to worry about
dying sectors, etc. and ext3 was the right choice? Or should I chose a
journaling filesystem? (the system will run as minimal communication server)

As there seems to be extensibe knowledge here about linux on flash
devices, two other questions:
1. Is it correct to assume that systems on flash devices need to run
without swap partitions? (due to frequent writing on these)

2. Is there any easy advice which parts of the directory structure
should better not be mounted on the flash? Or in which directories in
the linux structure will typically occur frequent write accesses? (E.g.
log-files?)

Is there maybe a HOWTO or anything discussing linux on flash in general?
~ I guess these are fairly typical questions...

Cheers,
Arik
