Does an Irish surname mean I can claim a family coat of arms?

No. In Ireland a coat of arms is granted by the Chief Herald of Ireland to one person, and it descends through that person's own line. It has never belonged to a surname, so there is no such thing as the arms of everyone who shares a name. What shops and websites sell by surname is a decoration: sometimes it uses arms that belonged to one historical bearer of the name, often it uses arms that belonged to somebody else entirely. If a named ancestor of yours was granted arms, that grant is a matter of record at the National Library of Ireland, which houses the Chief Herald's office. The honest version is more interesting than the mug.
