Yes, I also came to Rails from Grails. Grails has a strong service layer concept, and encourages to push a lot of business logic into stateless (and transactional) service layer. Something I've missed in Rails, so I started doing something like this implicitly by creating non-db backed model classes.
Also, I would suggest if you are going to use service objects, to use similar convention as with controllers, i.e. call an object authentication_service vs service. That will help to know where the original definition lives - i.e. is it a model or a service.
I ended up using the static version of twitter bootstrap.
according to docs on the github, just include
gem 'twitter-bootstrap-rails', :git => 'git://github.com/seyhunak/twitter-bootstrap-rails.git', :branch => 'static'
in your gem file.
