Question

Is it possible to set a download limit in the Ubuntu Software Center?

Also, is there is a way to download applications installation files for offline use?

Answer 1

Setting the bandwith limit on apt-get which is still what Ubuntu software Center and Synaptic use to get packages (I believe) is fairly simple. If you go into the /etc/apt/apt.conf.d directory you can add Acquire::http::Dl-Limit "70"; ("70" being the kb/s) in whichever parts of apt you choose.

Answer 2

You can download packages without installing them by using apt-get's -d option, used like this: sudo apt-get install -d packagename downloads the files for packagename. You can then run sudo apt-get install packagename offline to install the package. As far as putting restrictions, I don't know what you mean. You can make an account non-administrator so it prompts for a password of another user to install software.
