1) Hours and hours. A lot of cutting, trimming and other BS goes into installing even a QUALITY FMIC, what you bought there is not what most would call a quality kit (not even acceptable in my book), and therefore will probably have a LOT of surprises in store for you.
2) You'll have to do a lot of things to properly use that kit, I hope you have time and money to spare.
3) I'm pretty sure you made a mistake in buying this thing. Do you know why you even wanted an FMIC in the first place?
