Stefan,

You should look at section 1.2.4 Beams and Setting automatic beam 
behavior.  You might also want to check the section in Rhythms under 
Tuplets.  Here is your example again with a couple of changes:


\version "2.11.7"
{
        %% This sets your tuplets to cover only a quarter note
        %% so you don't have to type so many \times 2/3 {...}
        \set tupletSpannerDuration = #(ly:make-moment 1 4)

        %% These set the automatic beams to end on the 3rd
        %% 6th and 9th triplets.
        #(override-auto-beam-setting '(end 1 12 * *) 3 12 )
        #(override-auto-beam-setting '(end 1 12 * *) 6 12 )
        #(override-auto-beam-setting '(end 1 12 * *) 9 12 )
        \time 2/2 f'' 4
        \times 2/3 { a'' 8 g'' f''  e'' d'' c'' b' d'' b' }
}
