In general, taking the average across samples is not very useful, assuming that you want to perform differential expression. Instead, take a look at a package like the limma package to perform differential expression. As for multiple probes per gene, I tend to leave them as individual probes and not collapse them; doing so is not always the optimal approach, but it is quick and easy.
