Radius & 802.1x question

[Era]

Hello,
Could you please help me with following question :
1. I would like to setup secure auth on our several procurve switches. I tried to use Radius but it seems that it is not ready to provide security for auth, all requests are going to radius server in clear text. How I can enable any crypto method? Or need to use Tecacs+ ?
2. I plan to deploy some security policy and I need to check users hardware mac address (via Radius) and user password(via 802.1x) step by step. Is it possible to control hardware and user who is working on this hardware simultaneously?

Regards,
Alexey
