Glad you are now Cancer free. Like Ray said, the only dumb question is the one you don't ask. The guys and gals on this forum are fantastic and are eager to offer help or advice. When I first start scrolling, I also purchased the sample pack from Flying Dutchman. When someone posts one of their finished "Brags" on this sit they often credit the pattern maker as well as providing the type of wood used, finishing procedures and the blade they used. I noticed that the Pegas blade seemed to be the blade of choice by a lot of users. Now I exclusively use the Pegas blades. There is a size charts available that tell you what size blade to use with what thickness of wood. I tend to stay on the minimum side of what is required because I like to make the sharp angles where needed in my projects. When I first started scrolling I thought I would never use a spiral blade. After cutting my first piece trying the spiral, I have made them my "go to" blade. It's a little tricky starting out and getting use to them, but once you do, you'll love using them. When I'm cutting patterns with a lot of letters or straight lines, I'm almost certainly got a #2/0 Pegas MGT blade in the saw. Ray also pointed out that Denny Kneppan is a member of this forum and a dealer for Pegas blades as well as other scroll saw items. (Pegas Scroll Saw (artcraftersonline.com) You'll also find that Denny's customer service cannot be beat.
I might suggest starting with a few simple patterns. Steve Good has a catalog with several thousand patterns and a lot of them are easy to cut. (Scroll Saw Workshop Catalog (stevedgood.com) When you get the hang of things, jump on over to the pattern library on this site and check out some of the patterns there. You'll find they get a lot more complicated with a lot more fretwork. Also, you'll find that letters can be a little tricky. Just take you time, and by all means, enjoy scrolling!
