Transfer all ReSharper Settings between PCs
Solution 1:
Since the export option within Resharper is only for code styles, you'll need to be a bit craftier for all settings.
From Peter Ritchie's blog...
...the settings are stored in "%userprofile%\application data\jetbrains\resharper\v4.0\vs9.0". There are a couple of xml files in there that store your settings. Before you upgrade to the latest build, just copy those to another directory.
It's very likely that the format of these files has changed since the last build so copying the backups over the new version could possibly make Resharper to blow-up. So, use with caution.
I have Resharper 4.1 so instead of "...\v4.0\vs9.0" it's actually "...\v4.1\vs9.0" (obvious, I know, but worth mentioning).
I'm not sure about StyleCop settings, but this should work for most other settings (keyboard scheme, code completion settings, etc...).
Solution 2:
There is a R# settings manager plugin for resharper that stores all of this I think, including stylecop settings
