hello all,i want to thank any and all for useful help in advance

ok,i am having trouble with updating my suse 9.1--"couldnt cd to i386" is the error
i cant seem to understand how to configure my e mail,in windows i used mozilla/firefox
and cant figure out what e mail program i have,and how to get it configured.i know all my pop3 settings etc,just am lost as to how to get it done.
i need to know how to install Nvidia drivers
i need to learn how to install game patches for unreal tournament 2004.
i have purchased a book to help me learn basic linux things,and i can do all these things in windows xp,i just need some really noob help to get me up and running.so,per my new book,i have a rudimentary knowledge of the shell konsole,and run command.i dont understand x and what to do to be where it is off so i can get my Nvidia drivers.i also have ATI and Intel drivers to install,i assume they might have similar procedures.
also,how do i change from one runlevel to another,and back again?
and,when i get one machine set and working right,can i make a boot cd/back up cd and run it in my other computers and get most if not all the same changes to all in my network?or ,ultimately,would i be better off doing each one at a time?i am noob,i did try to search,and just wasnt sure of what i was looking for.i need basic info,links,FAQ's,and any relavant info,or other sources.i really like SUSE,and i need to get it up and working for my gaming,and forums admin duties before i delete windows xp

i am glad to have NO networking issues or any other problems i cant work out.i want to thank everyone for the help for my uber noob goober post!!
