Geordi also went from Lt. to Lt. Cmdr. and did not change jobs in between season 2 and 3.
Worf was sort of an fill in officer on the bridge before Yar was killed. But he did become Lt. Cmdr. while still being Security Chief.
Troi DID become a full Commander.
Dax was Lt. and became Lt. Cmdr. as science officer.
Bashir did get a promotion between season 3 and 4, Lt. j.g. to Lt.
Sisko was still station commander when he became Captain.
Kira became a Colonel between season 6 and 7, though she was acting station commander in those 3 months.
Tuvok... I don't remember there being a separation of the two roles for him, but either way, he was still doing the same job.
Not sure about Tom, but everything points to him still being lead helmsman. Ro was the helmsmam of the Enterprise-D and was an Ensign. Dialogue at the beginning of "Conundrum" seems to indicate she was a lead.
