Re: differencies between openVPN and openSSH
when you do it with openssh you create a socks proxy which you can reach via (normally) 127.0.0.1.
when you do it with openvpn you create a fully functional tunnel, which you can route some subnets or all internet connections over. you are also able to tunnel entire lans over it. With openvpn you get a virtual interface, with the option to tunnel ethernet (tap) OR ip traffic (tun) over. You can run openvpn over UDP, which has a huge advantage over socks when you wish to tunnel TCP traffic over it (see: http://sites.inka.de/~bigred/devel/tcp-tcp.html (from openvpn manual)).
If your only desire is to tunnel your web browser through a secure host, use whatever makes you happy... but when your needs grow openvpn does WAY more than socks can.

Basically, with openvpn you handle what you contact over the vpn with routing... with an ssh-tunnel you handle it on the application level by configuring your application to use the socks proxy.
