I'm new to computer forensics but I'm trying to figure out how to dump the data in the physical memory, maybe to a flash drive, and what can I use to browse that dump?  I was looking at win32dd and win64dd and possibly using volitility to browse the contents but not sure if there's something better to use or would someone can point me to training material

You could also use DFF see 2 minute video walkthrough

DFF is alright, nothing more than a GUI for most other tools. I like to use old school *nix tools via cli most of the times. I can do so from anywhere and the results are the same. It also helps keeping me on my toes via way remembering things.

Yeah, I like Memorize and you can make it portable too. I added it to my Iron Key USB flash drive as part of my tool kit. You just have to make sure to run it once from your flash drive with write-mode enable to let it copy some additional files.

Also, last week I had the chance to play around with Redline. I like it except that you need .Net Framework version 4 or greater to use it on your Windows machine. Currently, it's very slow in analyzing memory dumps and it doesn't work well with Windows 7. But hey, it's new and I'm sure that Mandiant will improve it and make it better. I do recommend for beginners to take look at Redline and use it because it walks you through with explaination on quickly detecting suspicious or potentially malicious processes and etc.   

Btw, Don, I can't thank you enough for the Iron Key flash drive. I can't live without it! Since I can unlock the Iron Key in read-mode only, it's perfect for incident response and malware forensic. You don't have to worry about your flash drive getting infected. I know it has been more than a year that I received my Iron Key, but I just wanted to say thanks again.
