While I don't exactly know the answer to your Flash problem, I do know how to disable Javascript, though.
To disable JS, find your Google Chrome shortcut (say, on your desktop or something). Right-click it, and go to Properties. In the "Target:" field, but "-disable-javascript" after the quotation marks.
For example, my Chrome shortcut looks like this (of course, your Chrome shortcut would have your username in it):
"C:\Documents and Settings\Bapa\Local Settings\Application Data\Google\Chrome\Application\chrome.exe"
To disable Javascript in (my) Chrome, I'd put it exactly like this:
"C:\Documents and Settings\Bapa\Local Settings\Application Data\Google\Chrome\Application\chrome.exe" -disable-javascript
I've also included a link to a helpful article in my references.
