Pertaining to your sixth point, some have suggested that the universe's current acceleration of its expansion obviates the universe collapsing (and therefore obviates the Omega Point). But as Profs. Lawrence M. Krauss and Michael S. Turner point out in "Geometry and Destiny" (General Relativity and Gravitation, Vol. 31, No. 10 [October 1999], pp. 1453-1459; also at arXiv:astro-ph/9904020, April 1, 1999
http://arxiv.org/abs/astro-ph/9904020 ), there is no set of cosmological observations which can tell us whether the universe will expand forever or eventually collapse.
There's a very good reason for that, because that is dependant on the actions of intelligent life. The known laws of physics provide the mechanism for the universe's collapse.
