gem help search yields:
-a or --all to search for all versions of a given gem.

PS C:\Users\CynicalRyan>  gem search nokogiri -ar

If by "local gem directory" you mean a directory containing gems you 
downloaded, then yes. Just type "gem install <gemname>-<version>.gem", 
and RubyGems does its thing.

You cannot skip compiling, however, if that is a necessary step, as far 
as I am aware of.
