Since there's likely some serious time and location dependence 
here, I suggest you get a copy of Pinheiro and Bates.

@Book{PinheiroBates2000,
  author =	 {Jos\'e C. Pinheiro and Douglas M. Bates},
  title =	 "Mixed-Effects Models in S and S-PLUS",
  publisher =	 {Springer-Verlag},
  year =	 {2000},
  address =	 {New York}
}

Since performing statistical consulting for free is a 
dangerous prescedent to the profession, I'll leave it
at that :)

Cheers
