Answer 1

there are params[:controller] and params[:action] that help you to know which action is current.

Answer 2

<div id='example_link'>
  <%= link_to_remote "Example",
      :update =>'view',
      :url =>{:controller => 'home',:action => 'bank'},
      :method => :post,
      :html =>{:id =>"cb"},
      :with => "'choose=' +encodeURIComponent('value')" %>
</div>

in your home controller

def bank
  # your code
  render :update do |page|
    page << "$('#example_link').addClass('highlighted')"
  end
end

in css

.highlighted{
  background-color: yellow;
}
