Both overrides
\set beatLength = #(ly:make-moment 3 8)
#(revert-auto-beam-setting '(end * * 6 8) 3 8)
are working at the voice context. When you create a polyphonic section
using the shorthand << \\ >>, you're creating two new voices which are
separate from the main voice, hence why the overrides have no effect.
In the case of the beatLength setting, you'll have to insert it (or a
macro to save typing and improve clarity) inside each polyphonic
section as required. You can't apply it globally, since you're
combining two voices with incompatible beaming.
As for reverting the auto-beam setting, you can either set it per
stave or for the whole score by adding the context options as follows:
#(revert-auto-beam-setting '(end * * 6 8) 3 8 'Staff)
#(revert-auto-beam-setting '(end * * 6 8) 3 8) 'Score)
\version "2.11.42"
\paper { ragged-right = ##t }
setBeat = \set beatLength = #(ly:make-moment 3 8)
clearBeat = \unset beatLength
\relative c'' {
\time 6/8
%turn off default autobeaming for 6/8
%this time in staff context, applies to any beaming on this stave
#(revert-auto-beam-setting '(end * * 6 8) 3 8 'Staff)
\setBeat
%this polyphonic section ignores the new beat length
