When I first started on this site, I kept seeing SWMBO in posts. Took me awhile to figure out this was She Who Must Be Obeyed. So, you can just refer to HWMBO
As for brewing, I will second RM-MN. You can brew good beer with extract, partial mash and all grain. That's pretty much the progression I followed. Partial mash is a good way to learn about grain characteristics without a huge investment in equipment. BIAB is a good way to do AG with a minimal investment. When you make the jump to AG, you will want at least a 10 gal brew pot.
Beyond that (and sanitation, which goes without saying), the things that will make the most difference in the quality of your beer are 1) pitching the proper amount of healthy, pampered yeast, 2) good fermentation temp control and 3) patience. If you are into IPAs, it is also useful to learn all the different ways to utilize hops - first wort hops, late additions, flame out hops, hop stand and dry hopping.
One last piece of my $.02 is that usually less is more when it comes to recipes. I think every brewer in their first year (including me) tries to create a Banana Pineapple Cinnamon Peanut Butter Belgian Porter (or something equally out there). Take small steps and learn what you like.
Oh, and anything Yooper says is gospel. She rocks!
