There were a couple of higher profile novels covering a second Falklands war that I know of:
Exclusion Zone by John Nichols - http://www.amazon.co.uk/Exclusion-Zone-Nichol-John/dp/034071879X/ref=tmm_pap_title_0?ie=UTF8&qid=1366982131&sr=1-5
Land of Fire by Chris Ryan - http://www.amazon.co.uk/Land-Fire-Chris-Ryan/dp/0099432382
I've not read them so don't know how good they are, but there's no questioning the two authors' experience.
I found this what-if article on the MailOnline website - http://www.dailymail.co.uk/news/article-2077813/Falkland-Islands-Prince-Harry-captured-600-soldiers-killed--imagined-Dominic-Sandbrook.html
A very funny potted history history of the real Falklands war written as if reviewing an implausible alternative history technothriller - http://www.changingthetimes.net/samples/brooks/review_of_the_alternate_history.htm
And talking of SF2 scenarios, how about this alternative history of the original Falklands war where we Brits lose. The detailed descriptions of the air/sea battles of 10th May 1982 are crying out for some custom missions. - http://www.changingthetimes.net/samples/coldwar/falklands_war_1982.htm
