I like the ideas about giving the characters a far deeper psychological background. To that end, I would eliminate the "perfect federation" concept and have far more interpersonal drama that isn't imposed by aliens.
Riker should also be cast by a younger actor and be more of an upstart rather than an organization man. His romantic relationship with Troi should be active, or at least on-again, off-again.
Tasha Yar is unnecessary with Worf on the bridge, just like the real TNG. However there should be a younger female character on the crew, possibly replacing Wesley. To that end, I would remove all the technobabble aspects and make Geordi a much more minor character.
