If you want to learn about microarray analysis, you should look into Bioconductor from R. There are a lot of packages and workflows like arrays.

You can follow my guidance, here: How do I convert Affymetrix ID names to gene names

You will have to modify the above code depending on which Affymetrix array that you are using. It looks like you are using the U133A.

Note that you can summarise expression values across probes targeting the same gene via the limma::avereps function - How to combine expression values of multiple probes for one gene?
