I am unclear on why you thought this clearance was unclear. You were
cleared to D95 and you were told to climb to 5000. What additional

Regarding the squawk code, it is not all that unusual to get the code
on the first call and get the complete clearance afterwards.

With the exception being the controller gave him a code and then said he
was going to look for his clearance. If he finds one it will have a
different code on the strip so either the pilot will have to change
codes or the controller will have to make an ammendment on the flight
plan. That's working too hard.
