I'm installing my first RAC and I was wondering if I should install CRS (we are still at 10g for compatibility reasons) then patch to before I install ASM (then patch) and finally rdbms (then patch)

or if I should install CRS / ASM / RDBMS and then patch to in the same order.

I would go "CRS / ASM / RDBMS and then patch to in the same order" just to be sure I follow the most typical way that others went before became available. But it's just me, your first proposition will work as well.

Both alternatives guarantee that at all times:

CRS version >= DB version
CRS version >= ASM version

A link to where Oracle make that recommendation would go some way towards making this a more useful answer :-) –  Jack Douglas Mar 21 '12 at 14:08
