Not sure if it will help, but you might want to check out Michael
Trott's Guidebooks (either the symbolics, or numerics).

http://www.mathematicaguidebooks.org/

Of course, if you have the cash, there is an AceFEM package on the
Wolfram site you might want to look at.

As a side note, you may not want to implement a pure FE code in
Mathematica as you traditionally would in a procedural language like,
say, FORTRAN, or C. Solving these systems symbolically might make more
sense for some systems when using Mathematica. Having said that, I
myself am very new to Mathematica and have not coded any FE or FD
projects, so take that into consideration. Personally, I would love to
see a side-by-side solution of an FE system (even a simple 2D Heat
Eqn) in a procedural language like FORTRAN and the corresponding
solution in Mathematica.

Hope that gives you a starting point
