Problem 1 sounds like it's a name resolution issue, especially since
you've indicated some of your clients are not using WINS, which is kind
of strange. The browse list relies heavily on broadcasts and NetBIOS
name resolution, which presents problems in a routed network like yours.
The way around this is to implement WINS and to ensure that EVERY SINGLE
MACHINE THAT CAN BE A WINS CLIENT IS ONE. Otherwise you get the problems
you're describing. WINS Proxy Agents might be a solution for subnets
with clients that can't use WINS.

Problem 2 is kind of strange. Authentication should be occurring when
you first connect to the server. Nonetheless, the server will have to
check local NTFS and share permissions when access to a specific share
is requested. Odd that the delay only occurs the first time. I take it
the delay occurs regardless of the number of files in the share? If so,
it points to some form of authentication problem as the likely culprit.
Hmmm... What's your DNS configuration like?
