hi,
so if you need help, then you can just connect to the irc channel :
irc://irc.opensuse.org/opensuse
opensuse comes with an irc client, so that should work.
next, i would not recommend using kde4 yet since it is very unstable and it just sucks compared to kde3. opensuse 11 works well, so that shouldn't be an issue. as for getting your network connected to a windows computer, you were a bit unclear what you wanted to do exactly. if you want to share files, then just install the samba packages in yast. you probably will have to either turn off your firewall, or allow the samba client to connect. for me, i just turned it off completely. then you should be able to see your windows machine's shares.
if you have anymore questions, then just post them, or go to the irc channel, its usually a lot faster for small questions.
good luck,
