After installing the Guest Additions I managed to get the screen resizing/ full screen functionality to work. However I wasn't able to share the clipboard between the Host and the Guest OS.
My next best option was using the 'Shared Folder' functionality which wasn't very intuitive

Some points of note:
Firstly, the shared folders are made available under /media/ directory in the guest OS
Secondly, you do not need to allow sharing of a folder on the Host OS inorder to access it from the guest
Thirdly, in order to access the shares your guest OS user needs to be a member of the group 'vboxsf'
My Host OS is Ubuntu 11.04 and the Guest is Ubuntu 10.04.3 LTS

Steps,
1) Start up and log in to the guest OS
2) Add yourself to the group vboxsf (System>Users& Groups)
3) Right Click the blue foder icon and click 'Shared Folders' or Devices>Shared Folders
4) Add a folder to share. Check make permanent (transient ie only available for this session didn't feel like working for me). Also check Automount.
5) Log out and back in to let the group permissions set
6) Browse over to /media/.. The folders that were shared should be available here

I was trying out VirtualBox on ubuntu 11.04 and I wanted to install the "Guest Additions" package in order to increase the screen size of the guest which was ubuntu 10.04.
So i got the guest os running and then clicked on Devices>Install Guest Additions (Note: the Devices Menu is on the common menu bar on the top in 11.04 and not on the window for Vbox)
A prompt asked me to download the VBoxGuestAdditions_4.0.4.iso and then another prompt asked to mount it..
Here i got an error

"Failed to open the CD/DVD image (then indicated the file path for the ISO)

Could not get Storage format of the medium (again indicated the file path of the ISO)

VERR_NOT_SUPPORTED"

I retried the process about 3 times but in vain..

Basically the iso file was not downloaded completely.. its about 36 mb and only 10 mb was downloaded before the prompt to mount came up.

The solution to this is pretty simple.
Click on install guest additions again.. In the prompt copy the url that its says its goin to get the iso file from.
Download the file in the Host ie ur desktop
Shut down the guest os
Configure the guest os to use the downloaded iso file as the secondary drive.. (under Settings for the Guest in Vbox)
Start the Guest os
Now the iso file will be available under places.. Autorun..
Restart the guest and autoresize screen will now be available..
