As I write this, I'm using 10.4 and plugged into a network with a
.local domain - it seems to be 'standard practice' in the Windoze
world to set stuff up as .local unless there's a real domain name to
use. I've not observed any funny behaviour with DHCP - but I did note
that in your original logs there were 60 second leases being offered
which may be a clue as that's far too short for a workable system.
AFAIK it's not possible (or at least easy) to disable zeroconf
altogether, and it wouldn't be advisable anyway as so much relies on
AIUI, the main issue is that you can't resolve domain names to
addresses in the local domain. There are some tech notes about it
somewhere, but with 10.4 it's apparently solvable by putting "local"
in the Search Domains box of network settings (for previous versions
it's a lot more involved).
