Regarding the SonicWall VPN client on 7 64 - there's a small change I needed to make for it to operate properly.
1.Install SonicWall
2.Reboot
3.Open device manager
4.Click View > Show Hidden Devices
5.Expand Non Plug n Play
Drivers
6.Open SonicWall IPSec device and set startup type to Automatic
7. Click start while you're there
8. Done
