Your chlorine looks fine with no CC. With your CYA at 30 to 50 (btw...which is it?) you ay want to get off of the tri-chlor and stick with bleach. No shocking is needed unless your CC starts rising or you are concerned about an unusual exposure (a baby with an accident or the like)

I would suggest raising your pH with Borax but you may want to consider some baking soda to raise your TA and pH together (if you are shooting for a TA of 100)

Here is an online poolcalculator that works nicely.
