I would go with the icecap k1 Nano skimmer over the eshopps. I have two and they work great and are easy to adjust. The way the eshopps works it will be a pain to adjust and dial in.
As far as a light, if you ever plan on upgrading I would just go with an Ai prime. A kessil A80 would be ok for that tank but I wouldn’t say for anything any bigger. Really the prime will be your best bet.
For feeding I just dose KZ lps aminos daily and feed the acans Hykari mysis shrimp when I feed the fish a couple times a week. You can do powdered food but I find they like meaty food more. Don’t focus on feeding them A lot or doing the aminos until your tank matures. I was dealing with algae and have not fed them or dosed aminos for a month and they look great.
