Essential accessories for a newbie

We will be bringing home our new to us 2013 Salem 26tbud in a few days. Lots of things to buy. Excluding the obvious household items needed, i plan on starting off with the following purchases to get me started. I was hoping for recommendations for a particular brand or model for any of the following items...
Water pressure regulator with gauge
Sewer hose with 45 clear elbow
Wheel chocks and leveling blocks
12v air air compressor with long cord
First aid kit
Tool kit
Extra jack, not sure which style
Power tongue jack
Replacement rear stabilizer jack as one is bent

For the water pressure regulator I use a watts brand that is adjustable, I think veal terra makes one also.
I use the rhino sewer hose with a generic clear elbow.
I have the yellow camco chocks, I also use x-chocks to help take the front to back movement out while camping. For leveling I used to use 2x8s and then found a set of Anderson camper levelers. They are expensive but same me from pulling in and out of the site multiple times to get level.
I made my own first aid kit, you can get a list of common items from the Internet and then customize it from there.
I put together my own toolkit, with new tools so that it can stay with the camper at all times. I have a good breaker bar and torque wrench, multimeter for electrical, spare fuses, some wire, and duct tape.
I have 12 ton bottle jack from autozone.
I just installed an Atwood 3500lb toungue jack. Other brands are Lippert and Bargman.
