As a deaf person, I have been introduced to friends and "blind dates" before; I usually prefer that they are at least partially warned... for several reasons. Those who may not be comfortable with my deafness, for whatever reason, will be weeded out before the meeting happens - and thus I am unaware of being 'rejected' based on something I cannot control. Second, it gives them a chance to mentally prepare a bit, so they know, for example, to face me when they talk -- which helps us both avoid the slightly socially awkward situation of them saying something, me not responding, and then them having to repeat themselves... and me having to explain the whole "I didn't hear you, I'm sorry, let's try that again..." In my experience, pre-warning has only been beneficial to me. However, Carrie's mileage may vary, as anyone's might.
I would tell Carrie that you know someone, Jim, who you think may be a good fit. Indicate that you want to invite both to a social evening to let them meet each other. Ask her what, if anything, she wants you to convey beforehand. Then go to Jim, and tell him that you have a friend that you want him to meet, tell him the date and time, and then relay any instructions Carrie wishes (look at me before you speak, bring a paper and pen just in case, etc). And hope there are sparks when you do get them together!
