Whether you can re-download music depends upon what country that you are in, and whether they remain in the store. If you can re-download it then it will show in the Purchased tab in the iTunes store app on your iPad.
For the songs that skip, I assume that they used to be ok. If they are also re-downloadable then you could delete them from your iPad and re-download them (whilst a song is still on your iPad it will show as 'downloaded' in the Purchased tab and not with the cloud symbol for re-downloading).
