Seems to me like your machine is running GNOME 3 in Fallback Mode. GNOME 3 Fallback Mode is intended for unsupported video hardware. This means that GNOME 3 is running in 2D mode and cannot display 3D 'eye candy' (stuff like Compiz). Other than that, it has no impact.

2) Would this incomplete and improper functioning of Gnome Shell harm my new computer? I bought this one because on my old laptop, a month ago, I lost the sound card, don't know why. Don't want to lose the Radeon on this one! And this is what concerns me most.
1) If it works from the LiveDVD, the likelihood is that it will work when installed. Ditto if it's updated. Some people recently have posted that they have blank screens after updating; you'll have to read their threads to see the fixes etc. Some of these people have NVIDIA or Intel GPUs, so their problem would not affect you.
2) No way. If you "lost" the sound card on your old laptop, that had nothing to do with whether or not the machine could run the full GNOME 3. You're not going to "lose" the Radeon GPU. It just means that the driver and/or X.Org Server do not support 3D graphics for your model. As there are both open-source and closed-source AMD ATI drivers, it may
be that trying a different driver would enable 3D graphics to be used, but I don't have an AMD Radeon HD 6520G so I don't know.

Did you use Applications > Sound & Video > PulseAudio Volume Control and make sure the correct audio channel is selected (Configuration tab)? Selecting internal audio, rather than HDMI audio, usually works. Did you launch alsamixer
(and press F6 to select you card) in a Terminal window to make sure the microphone is not muted? You have not posted details of all your hardware. Another possibility is that you have an Intel HDA chip that needs additional configuration: see the SL Wiki thread HOWTO: Resolve Problems With HDA-INTEL Sound Cards
. Is the microphone icon shown as muted or unmuted on the Panel? Right-click on it to change settings and preferences.
