I can only give you some references:

The book which handles linkage analysis the most detailed is
 
Analysis of Human Genetic Linkage
J. Ott, 1991,
2nd ed. Baltimore, John Hopkins University Press 

required reading for everybody who wants to understand what all these 
programs really do. Warning: it is quite heavy mathematically, so you 
need to have a firm grasp of Statistics etc. Also, the Handbook of Human 
Genetic Analysis (Ott&Terwilliger) contains for each subject a 
short discussion of the theoretical background. Just skip the parts 
discussing the programs.

And doing a search through the American Journal of Human Genetics on the 
subject of linkage disequilibrium will surely get you some good 
references. 

Hope this helps
