I taught myself to knit and crochet from books, and I like both equally well, although I crochet faster than I knit. I like some of the patterns I've seen that incorporate both. There is a book called Knitting Loves Crochet that is great. You can get the great lacy look of crochet and then pick up stitches and knit cuffs or a bottom in ribbing to get a more polished look. Or you and knit a sweater and crochet edging in scallops or whatever to get a great looking sweater. The sweater on the cover is really cute! Here is a link to the book on amazon.
