For the diff problem, you may have an old diffexpr hanging around with an outdated workaround for stupid cmd.exe quoting rules. Vim's handling of quoting on Windows was improved between 7.3 and 7.4 to work in more situations, but it also breaks some of the old workarounds. Installing a Vim version >= 7.4.103 will have a corrected diffexpr within the _vimrc created by the installer. Or, I pasted it in a superuser answer here: http://superuser.com/questions/697847/cant-run-vimdiff-7-4-on-windows-7

For the temp files problem, as I mention in a reply to your post on the issue tracker, the 'directory' setting ought to have fixed it. If it doesn't, it's possible you were relying on workarounds for issues fixed by the default values of 'shellxquote', etc. Can you see the problems if you launch Vim with "gvim -N -u NONE -i NONE"?
