I prefer to have all applications installed per-user, to ~/Applications/ rather than globally. The default location for apps installed from the Mac App Store is the global applications folder located at /Applications/.
Is there a defaults write com.apple.AppStore command I can run in the terminal, or perhaps a .plist file I can edit manually, to change this default preference?
A preference for changing the default view mode was added in 10.8:
I don't know any way to change the default view mode in 10.7.
There are several ways to do that.
The easiest way would be to install a Plugin which formats outgoing E-Mail and give you the option to change specific characteristics to you liking (Font, Size etc.). For that you should look into the following Plugins:
"WYSIWYG for your outgoing emails If Outlook for Mac, Thunderbird and other email apps can set the default composition font1, why can’t Apple Mail? With MessageFont, you can! MessageFont lets you set Apple Mail’s default composition font for new rich text outgoing messages. [...]"
"Universal Mailer is a Mail.app plugin that solves some issues when sending emails. It removes ATT00001.htm files, it correctly formats messages with attachments and inline images and offers an option to set the default font for outgoing messages. [...]"
Another way would be to change the default Font Size via the Terminal, f.e. in 24, open up the Terminal and type in:
defaults write com.apple.mail MinimumHTMLFontSize 24
That will change the Font to 24pt, but that includes the Page you want to forward from Safari if you choose 'Webpage'. If you just forward the Link everything should be fine.

if you not comfort enough to use default folder, yes you are still able to move the application which you had download from Mac App Store to another folder with two caveats:
