Looks like you are going to have a nice setup
I did not see an auto top up unit on your list or correct me if i am wrong. This will help you keep you salinity stable which is a must otherwise you will have to top the water up manually and when your away it wont be good.
I would also think about making your own saltwater as then you know exactly the way you have made it. A ro unit will be a good investmet and give you peace of mind.
You could also consider a STC 1000 temperature controll unit. These are great as you can put your heaters on them which will turn them on and off according to a set temperature. If a heater fails it will stop your fish getting fried. You can also hook a cooling fan up to it in the case your heaters are off and the tank is still not cooling.
When you are adding your live rock i would consider also what type of corals you are going to have so you can make a plan as where you will place them and what types
Best of luck on your adventure and remember take it slow i failed at this before and had meltdown and learned the hard way. My new tank is well over 2 months and still no fish just CUC a shrimp and corals
Look forward to seeing some pictures
