I've been working on this for hours... Solaris works but mouse won't move

Question

Edit: I should go ahead and say that I've looked at EVERY tutorial and guide and post I could find all over google, for literally hours. If you know how to fix this, I'm begging you to help me.
I have a Dell Dimension 8200, 256 MB RAM, Nvidia Geforce3 Ti 200 video card. The settings that appear when I press the "enter" button on the moniter say 640X480 with H.F.: 31.53 KHz and V.F.: 60.09 Hz.
For the keyboard and mouse:
Microsoft Wireless Multimedia Keyboard 1.1 ( Model 1014 ), Microsoft Standard Wireless Optical Mouse. Both of which wirelessly connect to the computer through the Microsoft Wireless Optical Desktop Receiver 2.1, which is simply plugged into the computer into the first USB slot.
My keyboard and mouse came from the same box, so they should both work...but only one does. Both worked on Windows XP, without installing any extra drivers, so it is not a hardware issue.
I'm using Xorg. Xsun graphics won't work for me--they come up as green and black scattered text. I ran the xorgconfig and xorg.conf was automatically placed in /etc/X11/. So, I assume that was done correctly... I chose Auto for Mouse Detection, the default mouse driver /dev/mouse/, Generic English 104-key for the keyboard, no for 3-button-emulation, no for special settings, yes for card selection ( I chose #19 Nvidia, #350 Nvidia Geforce will not work. ), #3 for Moniter selection, 640x800 for all options, and 16 bit I believe for all options.
I then rebooted, and the GUI worked fine and the keyboard worked fine. I logged in and got to the desktop, where I was prompted with some windows. The mouse pointer graphic was on the screen, but I couldn't get the mouse to work. I moved the mouse ( hardware ) back and forth repeatedly, despite my efforts the pointer simply stayed at the center of the screen.
It's almost humorous, right before I can read the keyboard shortcuts for Solaris manual while navigating the subchapters with the tab button and selecting them with the enter button( it was on the first layer of the windows that popped up so I could see it without needing to click on it ), the Solaris Registration window pops up a minute or two afterwards blocking out the other windows. I can navigate with the tab button in this window as well, yet the enter key does not have the authority to hit the buttons. My only option is to use a mouse...but wait--the mouse does not move!
SO TO THE POINT! Why won't my mouse work?!
I am completely new to UNIX based systems, so Solaris is my first one. I'm used to Windows XP, so just to let you know -- when UNIX commands are mentioned, you're speaking in gibberish to me. If I need to edit any files, please clearly explain how to do so--if I need to use a UNIX text editor etc., and what-not. Because as of now, I can only edit the files with the console.
Oh great...now this is appearing when I reboot:
WARNING - The following files in / differ from the boot archive:
/etc/path_to_inst
cannot find: /etc/devices/mdi_ib_cache: No such file or directory
The recommended action is to reboot and select "Solaris failsafe"
option from the boot menu. Then follow prompts to update the boot archive.
To continue booting at your own risk, clear the service:
# svcadm clear system/boot-archive
Jul 31 16:04:33 svc.startd[7]: svc:/system/boot-archive:default:
Method "/lib/svc/method/boot-archive" failed with exit status 95.
[ system/boot-archive:default failed fatally (see 'svcs -x' for deatails) ]

(See /lib/svc/share/README for more information.)
Console login service(s) cannot run
What is going on?

Okay I fixed it on my own by reconfiguring Xorg with a new mouse.
If anyone else somehow encounters this problem in the future, it seems like there isn't a driver for the Microsoft Wireless Optical mouse. If there is one, it doesn't come with the basic installation. Though, the keyboard works fine. The new mouse I got was a PS/2 Optical three-button mouse. It's pretty much your generic computer mouse.
