Sound OK to me.
The basic rule is, if your transformer does no smoke and faithfully converts voltages, whatever current it draws then on the primary is the good current. Otherwise, in case of shorted turns etc, you will either smoke or won't convert etc etc.
The idle current is simply 110V divided by the primary inductance's impedance which is your inductance in H, times 6.28, times 60 (Hz). Say, 1H inductance gives you roughly 370 Ohms which would create roughly 0.3A current.
