getting back to your questions...:

1. Are the negative question forms of the verbs formed by this way:
ingo mun boađe?
itgo don boađe?
iigo son boađe? ...
I've looked that up in my books, and it looks like you write the question particle as a separate word when following the negative verb:
it go (don) boađe?
2.The preposition "lahka" is used with Genitive, but where is it situated? - in front of the noun, or after it? "joga lahka" (near a river), "vári lahka" (near a mountain?
It's usually a postposition, which means it follows the noun.
Most of your sentences look alright to me, but of course I'm only a learner and make mistakes as well. I'm going to ask a native speaker soon, though, I sometimes talk to someone in Norway on ICQ who speaks Saami as well.
-We live near the river and the mountain. - Orrut goađi ja(?) vári lahka (how is "and" in Saami. I used the Finnish preposition ;P)
I'm not certain about the syntax of this sentence here, intuitively I would put the verb at the end, but that might be wrong.
"and" is "ja" in Saami as well
