No, modules are like Windows drivers (.sys, .vxd). Go around Device Manager and look at the Show Details tab for each listed device, then tell me how many "modules" are loaded. You don't disable modules unless you don't want the associated device to function -- which is usually not the case. Disabling a kernel module saves you about 16KB of RAM, which is just enough to display 1/4 of the star smilie in the edit page, so umm... it's not terribly useful
Services are like... umm... services. They are loaded in /etc/rcS.d or /etc/rc2.d, and by default, Ubuntu only does the BARE MINIMUM for a fully functioning Ubuntu system. You can disable services using the configuration tool, or by hand-manipulating these two directories, but of course disabling the wrong services, JUST LIKE Windows, can lead to a mysterious loss of some functionality, which can be difficult to diagnose.

I'm into applications.
From my standpoint, for example, Feisty is nice and fast on a 1 gHz Pentium, 512 mb, old 4G hard drive and 1280x1024 LCD. I'd like to see Vista on that system (no, I really wouldn't).

As said by Jdong, you won't gain much from disabling modules. On my system, there are a few modules marked as unused by lsmod which I don't know what they do or support but at most it would save me, what?, 500kb? You gain more by disabling some gnome applets.
You can gain more (not much) if you modify the startup services and some programs run by gnome on startup. For example, why load all those wacom and nvidia things if you don't own their hardware? Logical Volume Manager? I didn't know the live installer supported that. EVMS? The same. But when you start changing these things, you're on your own. Most obviously, don't disable anything you don't know what it does. On the gnome side, I usually disable updates notification (I'll aptitude update, thanks) and also disable restricted managers (read my sig). However, the most noticeable gain is that I feel better.
In short: did Arch run faster on my laptop? Yes. Did it take longer to configure? You can be sure.
Now on... Thinkpad T400

0 used != unnecessary module. It just means nothing is currently actively using it, or that the module does not mind being removed (i.e. it has a mechanism for disconnecting from userspace apps that use the device)
I'm not saying that Ubuntu doesn't have room for improvement... if we can find some app that is performing particularly badly, then profile it to figure out where it is doing worse than our competition, then we can fix it

Also, Ubuntu forces some choices upon you. I use KDE and Ubuntu Edgy updated from Dapper and earlier from Breezy. I had to install KDE metapackage, and with it I get a lot of programs I don't want, because I use only 1 kind of image viewer etc. You can't remove unneed stuff because kde metapackage depends on them.
You'll find yourself thinking more and more about Debian. Debian installs only minimal system by default and allows much more customizing. It doesn't force stuff down your throat. And since Ubuntu is based on Debian, switching 'back to roots' isn't a big deal.
