Stocking a new tank

[Koresample]

I am new to SW, had FW for years and need some guidance for stocking my tank. I have a Fluval Osaka 155 litre (41 gallon) that has 60 llbs of aragonite (the stuff that comes pre-seeded with bacteria) as well as 49 lbs of live rock that i purchased from a tank that was established for over a year. The LR has tons of coralline algae and in the 3 weeks i have had it, new growth is coming along. Water has tested good from almost day one (SG 1023, PH 8.2, NO2-0, NO3-0, Amn 0). I added a single skunk clown 13 days ago, had a slight diatom outbreak for about 3 days, but it is pretty much gone now. I have about 10 blue legged hermit crabs and an assortment of about 15-20 snails.

I want to add some corals in the future (SPS and LPS) as well as an anemone for the clown and i want a community tank as much as possible. In researching, i am thinking about a Yello and Naso Tang, another skunk clown, a Bi-coloured Blennie or gobies.
Thoughts on these fish (i am thinking a max of 6 for the tank size) and coral recommendations? How many to stock at once, how long between stocking each one, when to stock the corals. Are there any threads on this that i have missed.

thanks,

mike
