Get the specs of both frames so you can figure out if you are able to get the saddle and handlebars setup in the right place for you. If you can get it close to what you have or what you wish you had, then I'd go for it.
Good idea. You'd need the bottom half of a headset to get very precise measurements but even without you can get pretty close. Get some wheels in and put bike on a level floor. Then with a spirit level, some string, a weight and a ruler you can measure reach and stack of the bike. Also check seattube angle to see if the two bikes vary greatly there.

BB spindle width is usually more crankset-dependent. There could be a difference of BB shell width, however. One might be 68 and the other 73, for instance.
