Virtualbox Guest Additions in openSuse 11

[YourYojo]

Hi,
sorry for not beeing of help but having some more questions on this topic myself!

I just installed openSUSE 11.1 Beta5 with a Gnome desktop from a LiveCD image as a guest in a Virtual Box 2.0.4 VM running on a Kubuntu 8.10 host. Unfortunately installing the Guest Additions turned out to be a total pain as the guest didn't react to my USB mouse so I tried to install them by keyboard only.

But:
1. A welcome popup I couldn't focus/close with the keyboard took about 20% of the screen. (No Alt+Tab, Alt+F4, Alt+Ctrl+Tab, Esc...) Which meant I couldn't close it at all, which meant it stayed there the whole time...
2. Ctrl+Alt+F1-6 send me to a terminal on the *host* though Virtual Box had "cought" all other input before. Is there another way?
3. Well, I tried to work around this *** welcome popup in a Gnome terminal to mount the CD which didn't automount only to find out afterwards I'm anyway to dumb/inexperienced in using the openSUSE cli tools to activate the apropriate repository and pick the right packets. (My 1st time experience with openSUSE - no "gksudo"/"gksu" in openSUSE btw?)
4. It took me 20 min then to keyboard-fiddle in the graphical tools in spite of the popup. The result were 700MB of packages to install as a result of checking "kernel-source" and "kernel-syms" and "gcc". Really? I thought I had mispicked something, hit "abort", which froze the process and wrecked the filesystem

I'd be just too pleased if anyone had some advice on the above or some other best practice on how to befriend a virtual openSUSE as a newbie without a mouse.

thanks YY
