My main advice to offer is this. When you buy a boil kettle unless you plan only doing stove top brews get a 10g pot. If you get into the hobby you'll definitely want the 10g and as you increase your brewing expertise a larger pots comes with it. If you have a propane turkey fryer or would like to get one just buy a 10g pot to start it's cheaper than buying more than one pot. Then again having a second smaller pot could be handy. I use the 16qt pot that I originally bought for stove top extract brewing still for certain things. Also when it comes time to buy a pot check at a local restaurant supply store, sams club, or other box store. You can get MUCH better deals from those stores than brewing stores/websites.
Second since you will start out bottling I think it's important for bottling to be as easy as possible. There are two important pieces of equipment that make bottling tolerable if you ask me. One is a bottle tree and the other is a bottle rinser. I have the big tree as well for when I clean and delabel bottles. You fit more than three cases at one time on the tree. The bottle rinser makes sanitizing bottles a cinch. You just turn it upside down and pump the sanitizer up inside the bottle 2-3 times. I would have either quit brewing or bought a kegging system already if it weren't for those two pieces of equipment. The first couple times I bottled were serious pains in the ass!
