40g breeder

I was thinking that equipment wise this might be a good place to start! Any feedback and/or guidance from you more experienced reefers would be awesome!
Keep in mind I plan on keeping mostly corals and if a fish or two finds its way into the tank; so be it!
Tank-40G breeder
Light - ATI sunpower 4x39 or 6x39
Protein skimmer -Octopus' NWB 150 (This is from my 90 gallon) I will be getting the 160 extreme for the 90
Sump Refugium- 20g Long with three compartments ( i need some advice on baffle set up, lighting for macro algea etc.)
Return Pump- I currently have a mag 5 collecting dust but I have seen up to a 9.5 on a 40 galon before; which size is best?
Flow- Undecided - I am thinking of an mp10 MAYBE
Also, any plumbing tips or tricks would be awesome folks. My previous experience is with reef ready tanks and one hob overflow which I want to stay away from.

Tank $40
Light w/bulbs $420
Pro skm $269
Refugium $20
rtn pump FREE (Maybe)
flow Undecided
Misc exp. $100(sand, salt, etc)
Stand $50
-------------------------
Roughly $900 and this is before the flow is decided on
