You have the artist right -- Kunisada signed as "Toyokuni" from 1844/45 until his death in 1865.
The seals are date and censor seals, all associated with the commercial print censorship regime of the late Edo period. The left two seals are "nanushi" seals -- each belonged to a particular individual. The "double seal" system seen here ran from about 1847 to 1853.
The seal on the right is a date seal, giving the year and month of publication approval using the cyclical Zodiacal calendar system. This seal is "Rat 7" -- the seventh month of the year of the rat, in this case 1852.
For more on date and censor seals, search for "Nanushi Censor Seals" and you should find J. Noel Chiappa's page on the topic at MIT (for some reason I can't link to it directly).
