Bill,
Here's how I did it. Keep in mind that this is routing everything in your web browser thru the VPN and Proxy, not ALL internet traffic.
1. Make sure Hamachi is installed on your client (we'll call it laptop) as well as your server (we'll call it home computer) and that Hamachi can see the other machine.
2. Download and install FreeProxy on the home computer. You can find it here: http://www.handcraftedsoftware.org/index.php?page=4&action=file&file_id=5
3. Open FreeProxy and double click on the "ports" line item. Name can be anything, Protocol must be HTTP Proxy, Client Port is any port you wish to use (I use 8080 but it's up to you since nobody else will be able to connect to this proxy server anyways). Now here's the important stuff: Local Binding should be set to your home computers Hamachi adapter, and the IP address should be the home computers Hamachi IP. Remote Binding can be set to "use any adapter" and IP can be set to "use any IP".
4. On your client computer configure your web browser to use the home computer Hamachi IP as the Proxy Server and make sure the port matches what you put in FreeProxy for your HTTP Proxy Server port.
There you go, as long as the client to server Hamachi link is up your web browser now securely routes all your browser traffic back to your home computer before it goes out to the internet.
On a side note, you may want to use a Proxy Server configuration program to quickly enable and disable proxy servers in your web browser. No need to use the proxy server when you are at home, and this will just slow down your browsing anyways. I use a free product called Advanced Proxy Manager that once configured allows you to turn on and off the proxy settings in your browser with just a click.
