Ike haxton has some videos i think... I have moshmans book although i havnt read it yet, but given the 2p2 publishing and reviews from the community that itll be a good read...
Id also spend some time with an equity trainer (equilabs and pokerstove) to get a feel of the equity you will have in certain situations etc..
I would recomand Heads-up No-limit Hold 'em by Collin Mashman
