Those TT bars are means to put you in a very low, stretch-out position, on a TT bike. See the picture here. You'd be putting them on a more upright bike, so not sure what position you'd end up with, or how many usable hand positions there would actually be. Also, there are special brake levers, called reverse levers, made to mount on the ends of those bars and send the cable the reverse direction.
I think Zen probably has the better idea, of just adding bar ends to your current bars. But you could play with these TT bars and see how they might mount, how many hand positions you'd have, and if/how your current brake levers would mount. Might as well give it a try since you've got them.
Oil is good, grease is better.
