Hi Shaun, Welcome to the Village. As others have said go back and read as many newbie questions as you can. Also Utube can be your best friend and Steve Good has several videos and he is very good at explaining things. You can also reach him thru his website for some advice .
I use Primarily Flying dutchman blades which I buy thru Mikes Workshop and #5 ultra reverse is my go to. This blade is my personal choice. FD are less expensive and free shipping.
I buy most of my wood from LL Johnson which is in Michigan, you can buy wood online from Ocooch lumber. Sometimes you can find decent wood at Menard, Home Depot or Lowes and Amazon for the thinner Baltic birch.
Even if a question has been asked before don't be afraid to ask again. Everybody explains things differently so one explanation might not help but another's might.
Have you ever heard of the Ping test for blade tension? This is what a lot of scrollers use. Each blade is different as far as tightness goes so give it a try.
The more you scroll the more comfortable you will get (plus some frustrating moments) it's all part of scrolling. Just enjoy the process.
