Michael, Every kite is different. Some kites have attachment points, sewn on at the factory. Some don't, and you have to get creative. As for the damage, I think that was mentioned, when someone attached a tail, up in the middle of the spine, near where the bridle lines were attached. Attach the tail at the bottom of the spine.
As for the wingtips, make up a couple of short pigtails (3"-4"), and lark's head them to the loops, down near the wing tip, where the tension line or bungee is attached. Then lark's head your tails onto the knot in that pigtail. What ever you do, when attaching to wingtips, make sure you do the exact same thing, on both sides, to keep everything balanced.
As for the spine, you can usually attach something, like a pigtail, to the very bottom of the spine, by lark's heading to the bottom of the spine, or to the piece of velcro, that is usually found at the bottom. Here is an explanation, and photos, of how I made a tail attachment point, on my new Delta Hawk. I did this before I ever took the kite out to fly. Flew it for a while, then decided to try a tail. It worked perfectly, but of course, there's not a whole lot to go wrong here. Oh, and I didn't have any idea what, if anything, I might attach to this kite. All I was doing, was creating an attachment point (a pigtail) that I could attach anything too. I do this on a lot of my dual line kites............

Just don't get too hung up on there being a "correct & proper procedure", for doing this. A lot of this is simply trial and error. Again, don't forget, this is not "rocket science". We are playing with kites. Have fun - be creative. You can try just about anything, on a temporary, or trial basis, with a few simple pigtails, and if it works, great, if not, try something else. When you hit on a solution, then you can make some permanent changes, or "not".
As for attaching tails to the Rev, there's the upper wingtips, and the lower ends of the two upright spars, and maybe the center loop. I don't think that I would hook anything as big and heavy as a 100' tube tail, to any of these points, but a simple, light weight streamer, or two, shouldn't present a problem. Again, as on the dual line kite, if adding two streamers, make sure whatever you do, is balanced, from side to side.
An inexpensive item, to experiment with, is surveyor's ribbon. You can get a full roll of it (Lowe's or Home Depot), for a very small investment, usually in orange or pink, and then make yourself all kinds of permanent, or disposable tails. Again, just get creative, get yourself a roll of surveyor's ribbon, make up a few pigtails, and have at it. I make up tails, using several pieces (layers) of surveyor's ribbon (maybe 4 or 6 pieces, cut 8', 12', 16', or more). I put the pieces (one end from each piece) together, fold them over a couple of times for thickness, and insert a small brass grommet through the folded area, to create an attachment point for the tail. Then I take a sharpie and label them, up near the grommet end, (i.e. 6/16, which means 6 tails X 16 feet). When done flying, just fold them up, or simply put them in a stuff bag, and use them over and over. When they wear out or become frayed, cut them off, or throw them away and make up some more. Oh, and you can attach them using snap swivels (like used for fishing) that you have tied, or pigtailed to the kite, or just lark's head pigtails through the grommet, and then onto the kite, where you may have added another pigtail. There really is no right and wrong here, just use common sense, that is, unless the kite manufacturer has provided you with attachment points on the kite. If so, snap in there, or attach a pigtail. You'll figure it out Just try something, and if it works, great ! If not , try something else.
