That would again be a study in contrasts - no?
No, a study in contrasts would cover items that are dissimilar; a study in similarities would be items, which are in common with each other. All objects have properties that are similar to other objects and all objects have properties, which are dissimilar with other objects. When doing an analysis to list just the dissimilar attributes and not list the similar ones are well, just presenting half the story
But let me see if I can help you get started with just a few of the similar or comparative attributes between Christianity and Islam.
1.) Both have an absolute belief that their deity is the only true deity and that all others are false (you even demonstrate that similarity in the last paragraph of your post).
“There is only one true and living God.”
2.) Both have a belief that all others must recognize their deity.
3.) Both believe that they have a mission to convert all others to their point of view and that all others must worship their deity.
4.) Failure by others to do such somehow affects the believer’s world, which cannot be right or complete without all others believing in their deity. Although factual evidence is never rendered as to why this is true.
5.) Both have a holy book that they believe is the obsolete authority on all matters and that the accuracy of it cannot be questioned or challenged.
6.) Both have a hierarchal structure of authorities who are sanctioned to interpret said holy book and tell us what it truly means which here again cannot be challenged.
7.) Both are based on principles that were applicable, and possibly appropriate, for the historical time frame for which they were created in, but are very rarely interpreted in the current time frame, aka a hermeneutical approach.
8.) Both have martyrs in their belief system, which is the apogee that one can achieve as a testament to their faith in both religions, although such behavior is extremely egocentric and destructive it is regarded in both systems as highly valued.
9.) Both believers of each religion see the other religion as evil and doing the work of Satan. As an example, here is a recent post on this site by a freeper:
“There is no peace with the fanatical Muslims. Only killing them will be beneficial. The word must go out to all Muslims, that any provovation vis a vis assymetrical warfare will result in their death, or capture as prisoners of war (and then death). IMO we should keep killing them until they stand down. If necessary, kill them all. It's no more than killing lice and rats anyway.”
And here is a post from another bulletin board by a Muslim:
“satan will do anything as your Mr. Bush and his gang
are doing right now because they're friends of Satan.”
So there are a few I can think of off the top of my head that may help you get started. If however, you still need further assistance don’t hesitate to contact me.

I would still like to see a copy of your article if you can make it avaliable.
