It would help to know what is in $HOME/vimstuff/mymacs/vimenter.vim,
but even without that, my guess is that your vimenter.vim and
rubyenter.vim scripts make global settings rather than buffer-local
settings. For example, you are probably using :set rather than
:setlocal to make option settings.
That's also why you seem to find it necessary to use this:
autocmd BufEnter,BufRead,WinEnter *.rb so
$HOME/vimstuff/mymacs/rubyenter.vim
in addition to the FileType autocommands. You shouldn't need to do
that. You should only need to make most settings once when each
buffer is opened, not each time it's entered.
Further, you can simplify your _vimrc file by eliminating those
autocommands altogether and simply moving
$HOME/vimstuff/mymacs/vimenter.vim to
$HOME/vimfiles/after/ftplugin/vim.vim and
$HOME/vimstuff/mymacs/rubyenter.vim to
$HOME/vimfiles/after/ftplugin/ruby.vim.

:help local-options
:help ftplugin
