I will say the one thing I find disappointing about stretch goals like "an extra companion" is that unless I missed it, they haven't detailed how many there are in the first place. So saying I am going to get an extra one doesn't mean much to me as of yet. At least player housing seems like a tangible thing. That said I have already dropped a $100 on this game (and am fighting myself from increasing that to a lot more than I should), so they already have my money.
I am also in the group that doesn't want voice acting, with the exception of small things like what used to be in the Infinity Engine. It is too limiting to the writing. I would much rather have more more expansive dialog trees.
They said the game starts with 3 races, 5 classes and 5 companions. Goals are extra.
