Is my sentence correct gramatically?
You should have gone to your house to talk with your parents before you came here!

Question

Answer

Hello,

Yes it is.  Personally, I would probably use the preposition 'to' rather than 'with' but either are correct.

'...to talk to your parents...'

You could also say "before coming here".

Answer

Yes, it is totally correct. 
In spoken English we usually contract "should have" like "should've" and quite often sounds like shoulda.
