hey Manny, welcome to the "light" side ;)
No equivalent to SAMI or AFV; you can find older issues of Warship Modeler on sale Squadron monthly sales, you can pick a couple see if you like them.
Model Art magazines have great pics/references, but the text is in Japanese

Osprey New Vanguard has a few titles with broad subjects (i.e. german destroyers 39-45, British battlecruisers 39-45, etc).
Squadron/Signal has the old series of "in action", ww2 stuff. Their "ship" equivalent for "walk arounds" are "On Deck", centered on one ship (ie USS LEx, etc).
Classic Warships Publishing publishes an excellent array of titles, including Warship Pictorials. E-hobbyland carries them the cheapest I have seen.
Leeward Publications publishes short books called "Ship's Data", again for specific ships (ie USS Texas).
Most info we get online; dozens of web sites dedicated to specific ship types.
Couple great photo reference library:
US Navy Photo-History
http://navsource.org/
WW2 in color
http://www.ww2incolor.com/
for modern ships, one of the best sources are the official military web sites.
And dont forget the new Google/Life photo archive...
cheers
