Which version of Zbrush 4 are you using? In Zbrush 4r2 they introduced 'Dynamesh' which makes free form sculpting or base-mesh creation so much quicker/simpler.
I either use 'Dynamesh', traditionally for organic objects like characters, but if I want something that's a bit more precise, like armor, then I'd start working off a base-mesh that I'd create in 3DS Max.
As for helpful Zbrush info :-http://www.zbrushcentral.com/forum.php
ZBC is full of helpful info. Also look into artists such as Ryan Kingslien and Scott Spencer. They have books as well as DVD's which have a wealth of info in them, Ryan Kingslien has a youtube channel also.
