I'm not aware of any one book that has all or even most of the types of ACW arms w/ the info you're looking for. In fact I can only think of one off hand that has velocities. One thing w/ the "about 9 lbs" is that is correct because all of the arms coming out of Europe were hand made variation was consistant. I've handled quite a few original P53's and the weight & balance can vary considerably.
You might look up the various works by Claude Fuller in looking for velocities but off hand I don't recall which has velocities. Another option might be to take a look at the NSSA board and ask if anyone has ever compiled the info you're looking for.
The Standard Catalog of Civil War Firearms is an inexpensive compilation of most of the arms available w/ bare bones info on each and is probably as close as you'll get in one work.
US Military Small Arms 1816-1865 by Reilly is the holy grail, but out of print & spendy.
Firearms from Europe by Whisker is a good purchase but make certain to get the 2nd edition as it corrects some of the glaring errors of the 1st Edition. I believe Track of the Wolf carries some of the titles in their book section.
There are the other works but IMO those two are must haves if you are interested in the arms of the period.
