You can probably learn a lot from Beating the Petroff even though it's intended for the white side.  It's a great book using the main lines.  Har Zvi has some videos called New Ideas in the Petroff that he did for Chess.FM that might be useful.  I think you should just stick with the Kasimdzhanov DVD and print out the material if you want a hard copy.

The Shirov DVD is also pretty entertaining and he recommends the 6...Bd6 variation for a more exciting game with Black.  I played it some and I never got draws.

For a book source for Black I think Raetsky and Chetverik is your only choice.  Fortunately it's a pretty decent book.

What will you do on 2 Bc4 though?  How will you prepare for it?

I recently started using the Petroff (very low level, lots of online blitz) and I haven't drawn with it yet. I used to get more drawish positions with the Caro. 
Raetsky's Petroff book is good, in my opinion. I also have the Yusupov 'bible' on the opening which I bought a used copy of - intimidating, perhaps, but with plenty of useful exercises/sample games you can just dip into to learn from his annotations.  The more recent Yusupov book (Build up your Chess vol2) introduced me to the defence properly (with its repertoire building chapter on it) before I bought anything specifically 'Petroff'.  
I certainly get to play more Petroffs than Berlin Walls (one of my other opening experiments of recent years) which is encouraging. But there are also plenty of Four Knights games, of course....

I dare say that business about a forced draw is overstated.  If you were to say "in order to avoid the draw (I suppose you mean 3...Nxe4 4. Bd3 d5 5. Nxe5 Nd7 6. Nxf7 Kxf7 7. Qh5+ etc., though it isn't exactly perpetual check), Black would need to choose one of a number of lines which should probably lead to +=", I suspect it would be correct.  I certainly don't think this sort of consideration should preclude something like a Starting Out book (there have been books on the Petroff accessible to "club players" in the past).

i'm working on putting together a new repertoire, and i'm including the petroff as black. if you're interested, i've discussed my reasons for playing the petroff here -

so this petroff thing is the bane of 1.e4 at the top level, has a long history going back to pillsbury and marshall, totally sound and imho good for a beginner to learn because it has lots of open lines and 2-3 move tactics.

so imagine my surprise when i look on amazon to see if there's a book on the petroff, and i find that there's only a handful, all outdated, and all with rather mixed reviews. WHERE'S THE BEEF, MAN? the frenchies and the sicilians get peppered with endless literature, "starting out" books, books on sub-sub-sub variations, dozens and dozens of choices, heck, pirc and scandinavian have more literature than the petroff. how on earth has no one written "Starting Out: The Petroff" yet?

furthermore, here in the 1.e4 e5 section there is almost no discussion of the petroff whatsoever! the double muzio and the traxler and the frankenstein-dracula get more love than the petroff!   

so i have two questions, i suppose.

1.) is there a good book available that i can use to learn to play the petroff? i got a hold of kasimdhanov's DVD, and it's very good, but i can't scribble notes to myself in the margins on a DVD, i like books a lot better.

2.) why have chess book authors ignored this defense? i don't understand it - all the big boys stopped playing 1.e4, and it ain't because they're scared of the pirc or the scandinavian, it's the marshall and the petroff and the sicilian, right? so why all the books on these other not-so-solid openings and none on one of the most important?
