Okay. So depending on how much die-off on your live rock you had during transport, you may or may not have started your cycle. Typical suggestion is tossing in a raw (unseasoned) shrimp (like from the grocery store) and you let it rot.
I wouldn't add any pods until after the cycle is complete. Give them a place to hide in the tank and they'll keep their number up on their own.
Clean up crew goes in after the cycle (I always add cuc the same time I add my first fish0.
As for the fish...
Clown pair should be first (also added together). They're hardy little stinkers, so they're a good first bet.
Are you getting a mandarin that eats frozen already? Or are you going to be reliant on pods for feeding? If the latter is the case I wouldn't add the mandarin until waaaaaay down the road. Like nine months or so.
I wouldn't even keep a juvenile angel in a tank that size. They need toooooons of room to swim and (unfortunately) your tank just won't provide that for him.
