Yes, right order: load the library, then use it.

Something in your init file doesn't _parse_.  Most likely you're missing a 
right paren or something.  Use `M-x check-parens' in your init file.

You can put (setq debug-on-error t) at the start of your init file, or 
customize it to t.

You can start Emacs using the switch --debug-init, as the error msg suggested.

In general, when your init file has a problem, consider _bisecting_ it, to find 
the culprit.  Bisecting is a binary search - it's fast.  You can use `M-x 
comment-region` to comment out 1/2, then 1/4, 1/8, 1/16,... of your init file.  
With C-u it UNcomments one level of commenting.
