can't really say what type of film you should get as it's kinda like saying what type of music you should listen to. what I like might not be what you like which might notbe what someone else likes. each different film has it's own look and feel to it. how much grain, contrast it has. how sensative is it to different colors can all change the tone curve as well. each has it's own tone curve on top of that as well on it's own even.
best thing I can say is look around at different film online and see how the images come out and compare that to what you are looking for. thankfully black and white film though is usually fairly cheap and each film (excluding the fake black and white films that get developed in color chems) can all use the same developers.
that is the other thing also . different developers can change how the image looks as well so there really is no this is better this is best this is what works it's more of some fun and experimentation to find what works for you.
though places to go to get information you can try apug.org
for film and chems B&H photo and adorama have some stuff and better prices it seems then freestylephoto.biz. freestyle is more expensive usually it seems but has a greater selection.
