How do I run wiring to a shed?

I have a building that will be powering 4 shop lights and 4 outlets. Things that are plugged in are air conditioner 110v 5000btu, radio, occasionally air compressor, other power tools(nothing big), and smaller things. I went to ace to get supplies and ask what I needed and was told I need a 30 amp sub panel ran to the shed with 10-2 or 10-3 wire ran from the main breaker panel (house). I was given a 15amp and two 20 amp breakers for the sub panel, 15 to power the lights, one of the 20’s for all the outlets, and the other 20 for the air conditioner. Does all this sound correct? I need to know if it is then do I need to wire strictly all the outlets (besides the one powering the AC) to the 20amp breaker and all the lights to the 15amp breaker? And the last 20amp breaker to the AC alone? Thanks in advance.
