I work as an IT consultant to small / medium businesses, so am the IT Manager and IT staff rolled into one for clients. The Axim is a HUGE tool for me. Things that I find useful, that hopefully may be of some help to you:
-- eWallet - for keeping any site-specific info that you feel happier about having encrypted / password-protected
-- Pocket Informant - for tracking tasks and contacts
-- PhatNotes - for note-taking
-- XS Forms - for creating database forms for things like asset tracking and such - their is one of their pre-designed forms just called 'IT' which is a pretty handy tabbed form for collecting username, hardware info, OS version, network info etc
-- WiFiFoFum - if you ever need to keep tabs on wireless access points
-- TimeTracker MX - for time & billing tracking
-- The in-built Terminal Services client
-- If you really want to get slick about remote management of servers and use a dedicated, secure app for that, tailored for PDAs, check out MobileAdmin - I did a mini-review of it at:

Guess it all depends on what you're up to in your role, but hopefully some of that may be of use.
