Me too. Two, that is. As all your entries (but two) are disabled then you are not missing them running. I don't think it would make much difference if you deleted the entries, but it would make the list a lot cleaner. I don't know if you can get them back without reinstalling the relevant program, but if you're managing without them I wouldn't worry about that. Personally I prefer launching progs when needed, to having them autostarted, which is what the manufacturer wants you to do. Just about any of these programs can be started from the Start/Programs list.
I would take the advice and stop Zone Alarm and see how you get on. I use the XP firewall set to no exceptions, and the routers firewall set to whatever its default is.
How many processes do you have running? I have 23, but that is admittedly lean. You can Google the entries (except syshost) to find out where they came from. Go to your Services page (Ctl Panel etc) and set to manual those that you don't want. There will be some that obviously need stopping (from 3rd party applications) and other XP stuff that you don't need. As an example I have stopped and set to manual:
Ati Hotkey Poller
Automatic Updates – (Revert to Auto/Started when doing updates)
Computer Browser – (Should not be running, change to Manual)
Error reporting Services
Help and Support
Secondary Logon
Server– (Should not be running, change to Manual)
TCP/IP NetBios Helper
Web Client – (Do not attempt to stop, will stop at next boot)
Windows Audio
Windows Time
Windows Zero Configuration (required for wireless connection)
Workstation
There may well be others to stop, and stopping some of these may make no noticable difference.
Many of these things apply to how you want to run your pc, so there is no set of rules that will apply to everyone. Do a little experimenting, a step at a time and rebooting, and see how you get on. I don't network devices, play games, download music stuff, or message anyone, so your needs will be different.
