file sharing win98 machine to new ibook

[question fear]

I have read through the forums and come across some advice on how to share files between windows and mac computers (have been trying the method described here (http://forums.macrumors.com/showthread.php?threadid=22749&highlight=file+sharing+between+windows+and+mac)
but no luck. I can get my windows computer to find the mac, but then it asked me for a password. i tried my login password for the ibook and failed. do i need my windows computer to have the same name as my os x one?
also, we have a wireless network in my house and that is what i have been using to connect...should i use a physical connection? what is the difference between a crossover cable and an ethernet cable? Also, once ive established the connection am i going to need a password then too? Finally, is FTP an alternate option?
One other question on the ibook (its brand-new: just got it yesterday); how do i set up the power adptor with the extension cord? i tried popping the pronged end off but it seemed really tight and i didnt want to hurt anything.
Thanks in advance for any advice i get.
Sincerely;
Carly

System Preferences:Accounts:Login Options:Edit User:Allow User to log in from Windows

then try your pass again

I tried that and it did not work. I feel like I should restart my win98 machine again. in that it seems to fix all sorts of inexplicable problems. However, assuming that fails, is there any other option?

and as for the power adaptor thing, i figured that out too.
I LOVE MY MAC!
