Hello Walter,
On your first question I've sent answer in your other ticket.
About passing the passing of arguments to the tests you can do two things:
1. If you run the tests in the same contexts you can set/get arguments from withing your code:
http://www.telerik.com/automated-testing-tools/support/documentation/user-guide/code-samples/general/extracted-variables-in-code.aspx
2. Store your arguments in file and manually read/write values. This opting will work if you choose different execution contexts via the RunHelper.Test().
Hope this helps.
All the best,
Nikolai
