I was wondering, is the entire joyo kanji included in RTK1?
Almost; there is one missing, 璽, which is RTK3 no. 2075. It's pretty rare.

I've been considering just learning the joyo kanji for a while. Is that OK or is there a good reason to finish the entire 2042 in the book?
I would say learn the whole book. Many of the 98 characters above are included because they are either (a) Useful as building-blocks for other kanji (e.g. 吾, ヒ, 頁, etc) or (b) Are very common in names (e.g. 藤, 岡, etc).
