First of all, you NEED test in this cycle. Without it, you are going to be shut down and feel pretty awful. Second, this is a higher dose for a first time tren user. If this is your first cycle of anything, I'm going to say that this is a very bad idea. If so, stick with test at 350-500mg and if you want to add in some dbol, 25-30mg is plenty, taken as a kick start for the first 4-6 wks of a 12 wk cycle. Also, PCT starts 2 wks after last test shot.
As for using test, tren and dbol, this is a powerful combo for an advanced user, It'll give good strength and size.
