PCI-E 2.0 is reverse compatible that means a motherboard having PCI-E can support a PCI-E Video Card.
Yes, the PCI-E interface is backwards compatible :)
More details would be required to answer this I'm afraid. Ie the model number of the motherboard. From here, we can be of more use to you.

Research your card and the specs for the motherboard of having a AGP 8x 1.5V the answer is, Yes. It will work.
Yes, it works fine. I have the same motherboard and video card and it works flawlessly!
Yes, in order for a computer to work at all. A motherboard holds all the hardwares; e.g. CPU, video card, sound card, etc.. which is why it is called the "mother" board

No it cannot you will need to get a agp card or upgrade your motherbord.
Any PCI Express card will work.
I have a Lenovo Mahobay motherboard also but recently i purchased a video card. I didn't work in the motherboard along with three others i would suggest just getting a good one from newegg.com for about $120 that is what I am doing
You need to install a sound card driver which you can find on the motherboard/computer manufacture website.
