Use Super One Click to get root access on the device. If the process hangs at "Getting mount point", open Task Manager and kill both running instances of adb.exe and restart Super One Click if necessary.
Install AdAway, a free (and open source) app from the Android Market - it updates the hosts file with entries from several host file sources on the web and runs a local server to return nothing when any of those hosts are queried. (The same as what HostsMan/HostsServer do for the Windows PC.)
