TPFAP vs. Harrington

[AceHiStation]

I'm a primarily cash game player with some multi-table experience. I have read Supersystem and Cloutier's Tourney book. I don't really use much of either. Anyways, I'm primarily a cash game player and can usually be found playing 2/4NL. My tournament experience includes several supers and quarter million tournaments, as well as some smaller buy-in online tournaments. My best finishes have been 9th in a super(750+ people) and 1st/60th in a live tourney at a bar(was a joke).

Anyways, I just wanted to give you my background. I'm flying out to California for a wedding this weekend and figured I'd get started on some reading. I've just picked up Harrington on Hold'em and Slansky's TPFAP. I was wondering if anyone recommended reading these in a particular order, which you found more useful, and why... maybe even sections to pay more or less attention to.

Thanks,
