Setting up a new lab, some questions

I want to setup a small 2003 network. Basically, 2 2003 servers and 2 XP clients is all I plan on doing. The only VM software I've used is Virtualbox. So I have decided to use VMware since it seems to be the standard most used. My questions is this.
Should I use Vista or Ubuntu as my primary OS to host the VMware software? My dell desktop has a Pent 4 3.0, 3 Gigs of ram, brand new 320 Gig hard drive.
Do I need VMware workstation, ESXi, or Server 2? I'm a little confused on what exactly I need to download. The Ubuntu forums says to use Server 2.
I plan on taking the exams for MCSA -> E. I'm also planning to use my Laptop which has Vista so I can put the 2 client VMware guest XP clients on them if needed. The laptop and desktop will be connected via a hub until my CISCO gear comes in March.

If you're just using it as a lab to test things then workstation or server will do. If you want to actually run something long term and unattended then server.
From a cost point of view, use server or ESXi since it is free.
ESX will take over the entire machine. There is no host OS. You'd be dedicating the machine to running ESX.
So I don't need to install Ubuntu because ESXi is the OS?

What remote client do I need to manage the ESXi?

The ram and hard drive work and is not DOA, thank goodness.

I installed Ubuntu and VMware Server 2. It took a 30 minutes to figure out how to login. I finally saw in the authorization-template.xml file that the login username was root, lol. Now I am installing win 2003 trial. VMware Server 2 is a little buggy or my system is really at the low end of what you should use. It took 2 tries to create a VM. The first time, it just would lock-up when it got to the CD/DVD part.

This is a Ubuntu issue. You have to press ctrl+alt+ins (insert on the keypad) to login.
