I dont think you need to do anything special.
As long as you have the telerik.web.ui.dll in your local bin folder you should be good to go.
I am assuming you have your own copy of the telerik suite. installed on you local dev machine, then you build your project and publish it to a precompiled location on your local drive ) it will remove all .cs or .vb files and just leave all the .aspx files and the code-behind all compiled as dlls in bin folder along with any other dlls u have (telerik included in this case)
then you take the whole folder from your precompiled folder and ftp it to the discount asp.net site. The bin folder will have the proper dlls
I have done the same in the past and this q1 should be no diff.
Thanks to Telerik
Let me know if u need details.
