Questions from an improving player

[HotPockets]

After reading a lot of poker literature and frequent these forums, my game is definately improving. However I have two questions. Can someone please elaborate on what exactly Reverse Implied Odds are and what kind of hands have reverse implied odds? Is there a certain book that outlines this idea? Also, upon going through NLHTAP Sklansky and Miller make a point in saying that Big Bets and Big Pots are for Big Hands. Do they mean that certain hands are geared towards winning larger pots preflop? Or are the authors trying to articulate that you should not being going broke with top pair? This whole concept is something I'm having trouble with. Is calling a raise and a cold call with something like 87s or 98s in position a negative EV play? In limit that may be the case, but in no limit your oppponents's stacks are in constant jeopardy so your implied odds are considerably higher. Any help on clearing these two points up would be a great help.
