Your example is entirely too complicated for me to parse in the time
available, but I have a few questions that I hope might help:
First, have you examined str(fit.lme) plus all the other help pages
listed under See Also in the lme help page, especially lmeObject?

I am trying to use lme to fit a mixed effects model to get the same
results as when using the following SAS code:
proc mixed;
class refseqid probeid probeno end;
model expression=end logpgc / ddfm=satterth;
random probeno probeid / subject=refseqid type=cs;
lsmeans end / diff cl; run;
