Thanks.
The thread on /tech/ is filled with info on tor, proxies, etc.

Has a good explanation on tor though vpn, vpn through tor, etc.
Imo TOR -> VPN OK.
VPN -> TOR BAD.
Proxies are also not that good, especially the free ones. They could claim to keep no logs yet log everything. Watch out for "high anon" proxies. 90% of the time they're honeypots. But as long as you are using your VPN and websites that support HTTPS You should be okay with proxies. I personally avoid them.
