The online resources for fabrics is vast! Request swatches and have fun!
I used to spend hours at pouring over pattern books at JC Penny's. (Yes, Penny's had a fabric department. There's a whole new crop of pattern-makers out there, and the classics still exist.
You'll notice that some of the fabric sites also carry thread, but you'll need resources for other notions and your equipment. These are great, JoAnn Fabrics (in the Fabric section - carries a lot of notions and equipment as well.)
These are fun YouTube channels with a lot of personality and “how-to” info.
These are the books I keep on-hand form reference. Between the three books basic, intermediate, and advanced sewing is covered.
