LOL, you will be just fine!
You are not sounding stupid. Every question is a good one!
Think if this, the fish that we have at our LFS have to be transported there through truck loads. So these fish can survive a little 10 Km trip, lol.
Just though all your decor in a bag or something that is clean. You will not hurt the rocks or anything. You can if you want, when you get to your new place, just poor hot water over your rocks/decor to clean them off, but this, I think, is unnecessary.
Get some of those bags that your LFS has, I bet they will give you a few if you ask them. Fill the bag with about 1/3 water, put the fish in the bag and then close the top of the bag really fast, which will "catch/trap" the air inside the bag. Just like your LFS does when you buy new fish. Then tie the bad closed or put a rubber bad to around the top to keep it closed.
I would only put one fish in per bag, just to reduce the stress. But, if you know for sure that the fish will be fine together, then go ahead and put more than one fish in per bag.
Yes, you can use a bucket to transport the fish as well. Just make sure it is clean and free of contaminants
If you can save some of the current water that is in your tank right now if you want. Put like half or so of it in a bucket, and then when you are re-filling the tank at you new place, just use some of your old tank water.
^^If you do not want to do this, you can add all new water to your tank, just make sure you use a water conditioner and add it to the water.
Feel free to ask as many questions as you want.
