It's quite possible that some of these numbers you won't be able to find, period, unless you actually contact a publisher of like size to yourself and are able to strike up a dialogue. The drawback, though, is that it's a competitive market, like any other; they might not be willing to share information that could help a potential competitor to hurt their own business in the future. If you're thinking of going into the business yourself, you might only have to make educated guesses and budget accordingly; for instance, ask a local trucking company how much it costs to pay a driver and load the tank to make a trip from one end of the country to the other and calculate the mileage estimates from there.
Even then, it's all just guesses.
What you'll also probably find is that a good number of times you'll end up outsourcing or subcontracting various aspects of the business. Unless you intend to buy your own trucks - be they 20 ft. box trucks or the big, 50-footer container trucks - you would probably be better off contracting a professional trucking outfit to do your shipping for you. At least then, however, your costs are negotiated up front and fixed via the contract; if anything varies depending on demand, that number is still known. The company also would handle all the licensing and maintenance that goes into the business (and the licensing can get extensive and very expensive; trucking schools cost - on average - four large up front, and we haven't even talked about automotive maintenance on those beasts).
#3 comes in a similar vein; this can depend on whether you're going to buy your own warehouse lock, stock, n' barrel, or if you're going to rent storage space. Either way, there could be equipment involved: pallet jacks, walk-behind or even riding forkifts, fuel and electricity and maintenance considerations for those forklifts, labor to run them... inventory management and personnel. Climate control and roadway access for trucks. Etcetera. All of that goes into cost considerations.
If, on the other hand, this is purely research for a report or some kind of essay on the business (I'm losing the correct word here), then you might have a better chance of getting the other numbers from publishers who could be amenable to shedding some light on their business. Many of the "hardware" numbers you can possibly figure out via searches and estimates from various online catalogs and manufacturers, not to mention local truck companies who might just be looking to expand their business.
In general, though, expect to meet opposition, as a lot of that information is sensitive to the way publishers do business. If, for example, it were to get out that one publisher is able to print for substantially less than another - and yet they both charge the same price on the shelf - it could lead to a lot of backlash against the former publisher. You have to be careful the way you word things if you want to get information directly from them.
Otherwise, you're more likely to either have to dive in headfirst and find out the hard way, or... just make a guess.
