Welcome to the forum Herb. It is knowledge and honing your brewing process that makes great beer however, not equipment and software. Many, many homebrewers make award winning beer on propane systems using picnic cooler mash tuns and I know of at least one homebrewer who has brought home gold medals making extract beers.
The first thing you want to do with Beersmith is sit down and create a custom equipment profile. Yes, there may already be a Brewzilla profile in the Beersmith equipment list and yes, your friend may have given you the settings he uses for his Brewzilla. But those profiles included in Beersmith were submitted by other users, and like your friends profile settings, they work great for them. You are not going to use the same equipment in exactly the same way. Something as simple as using hoses of a different length will change the amount of liquid volume in that portion of the system, how vigorous you boil will affect evaporation losses, etc. For that reason it is imperative that you create a custom profile made specifically for Herb.
Here is a video tutorial that will walk you through the steps. That, plus the combined knowledge of people in this group will help get you set up and brewing your own awesome beers in no time. Welcome! https://youtu.be/HwEbjOt8OR8
