 Re: How come we can say "Since I've know Jane...
I've means "I have." This is the perfect tense and requires the (usually) n-ending form of the verb:
"Since I've known Jane..."
Come is an irregular verb, it does not change in the perfect tense.
Your sentence: "...since I've come." is correct English.
