Help me please.

I've moved tanks more than a few times across the city and have found that for those short trips that you can load it all into rubbermaids or buckets. As soon as you get home though, get the heaters back on with the powerheads.

GO SLOW is the name of the game. Take your time, don't rush so you don't make mistakes. You'll do just fine. Like above, get new substrate but keep a cup of the old stuff to "seed" the new stuff.

Have fun!

*** Just re-read your post. Sounds like mostly fish so it'll be a fairly easy move. Is it fish only or do you have corals as well?
