As far as deca: I'd try npp (Nandrolone Phenylpropionate) before I tried deca, though both are good. Keep your doses low and not what a lot of people tell you: you don't sound like a massive-goaled beast nor a wannabe high dose kid so 200-300mg is good on nandrolones. You're get a big bump in anabolism, performance and recovery.
As far as Anavar: I'd dose at 40-50mg a day for your goals.
What I would do is try npp for 6-8 weeks, then just trt for 3-4 and then try var for 6-8 weeks, then just trt and go from there, try mast at 300-400mg a week, then try combos based on what you want,like,and goals. I love 8 week "blasts" with a short "off" time. I'd stay away from Tren unless physique is your only goal as I find it ruins performance, mood, etc. But you'd probably want to try it once and see for yourself, 250-350mg a week is plenty. Note that my recommendations are based on your trt dose with all the compounds.
