Just take it slow. Things can go bad quick in such a small tank. I had a green clown goby in my 5.5 nano I moved him to my main tank and he immediately grew a ton. I think you are getting to the limit of tank size to keep fish in a nano. Because it is real easy to overfeed a tank that small. So I think I underfed him. I am keeping my 5.5 fishless for the time being. Don't tell Wit but a bought a decorator crab last night. he is a super cool critter. I hope he pulls some polyps and zo's to put on his back.
I think you have a good setup I think you should up the LR to 7lbs because you are going skimmerless. I don't think it could hurt.
How much sand are you going to run? I have just a little. I really don't know what is ideal in a nano.
aquatic ecosystems sells these real small cheap in tak skimmers that might work great to run once and a while on your tank.

I have been tossing around buying one for my 5.5
have fun
