Unsure which two you mean by both, but if you only went for the first two, I'd recommend picking up the third, being Holdem on the Come. The first two give good advice for your whole game, but focus on preflop play for a lot of the material. Holdem on the Come looks more to the postflop action, which is a very important part of profitable limit holdem.
Also a factor to keep in mind is that these books seem to have more of a fishy player set in mind. During the poker boom these books would have you murdering your table like you wouldn't believe, now it seems in live play the fish have a bit of an idea about odds
and whatnot. So keep in mind during your limit play to figure out who looks fishy, but maybe is just adjusting their opening range wide, and playing correctly based on their pot/implied odds postflop. Seem to be a lot of them. Good luck.
