Don't be discouraged with pattern reading. Like learning a foreign language, it gets easier as you go on. You've already learned about k1p1 ribbing and completed a hat so great success so far!
For seed stitch, you're going to do just the opposite of ribbing when you get to row 2. For an even number of sts, you'll end row 1 with a purl, turn and begin row 2 with a purl. Your pattern for row 2 is p1k1. Again it helps to look at the next stitch on the left needle. For seed stitch, if it looks like a V, purl it and if it looks like a loop or bump, knit it. This'll give you the nice bumpy look of seed st instead of the aligned columns of ribbing.
