Question like this are better served on the bioconductor mailing list.
Nonetheless try this
ALL <- topTable(fit2, coef=1, number=Inf)
ALL$SYMBOL <- unlist(mget(ALL$ID, hgu133plus2hsentrezgSYMBOL, ifnotfound=NA))
Here ALL is the output from limma for differential expression (ALL$ID is the probe on ENTREZ centric cdf from brainarray).

Subject: [R] hgu133plus2hsentrezgprobe library
Hello R community,
I am processing raw Affymetrix CEL files and I am using the Michigan custom
CDF library hgu133plus2hsentrezgprobe. I have been looking for
documentation on the function that it contains...I am specifically
interested in converting probe names to gene symbols. Does anybody know
where I can find it?
Thank a lot!
