That ayah says "Salamun 'ala ilyasin". This view is backed up by the fact that previous and the ayaat that come after consist of "Salams" being send upon prophets/messengers.
In regards to saying R.A after Ali , Sunnis do it for all the companions. We add R.A even after the name of the ten who were promised paradise (Ali is part of the 10) such as Umar , Uthman, Saeed etc etc. It's not 'stupid', its merely asking
And verily, Iliyâs (Elias) was one of the Messengers (123) When he said to his people: "Will you not fear Allâh? (124) "Will you call upon Ba'l (a well- known idol of his nation whom they used to worship) and forsake the Best of creators, (125) "Allâh, your Lord and the Lord of your forefathers?" (126) But they denied him [Iliyâs (Elias)], so they will certainly be brought forth (to the punishment), (127) Except the chosen slaves of Allâh. (128) And We left for him (a goodly remembrance) among the later generations (to come) in later times; (129) Salâm (peace) be upon Ilyâsîn (Elias)!" (130) Verily, thus do We reward the Muhsinûn (good-doers, who perform good deeds totally for Allâh's sake only - see V.2:112) (131) Verily, he was one of Our believing slaves. (132) And verily, Lut (Lot) was one of the Messengers (133)
Allah to be pleased with the good deeds of the greatest generation of this Ummah.
