[BioC] which genes to choose for being truly differentially expressed from a long list

Dear All,
I used LIMMA for a dataset on Human plus 2.0 arrayto get fold change values for differentially expressed genes. I have a long list of 500 some genes with fold changes > 2 from the topTable function. How can I select genes which are most differentially expressed from this list?

Thank you,
