Are you specifically talking about the objects of verb-nouns? Generally speaking, the genitive is used except with
indefinite objects that are
further qualified by some sort of modifier. Thus:
Tá Caitlín ag léamh leabhair. (indefinite, not further qualified)
Tá Caitlín ag léamh leabhar staire. (indefinite, further qualified)
Tá Caitlín ag léamh an leabhair. (definite, not further qualified)
Tá Caitlín ag léamh an leabhair staire. (definite, further qualified)

Tá mé ag ithe ubh.
or
Tá mé ag ithe uibhe.
Both are, depending on dialect. In some varieties (e.g. Muskerry),
ubh is treated as a masculine noun of the first declension. This means that
ubh is both the nominative singular and the genitive plural while
uibh is the nominative plural and genitive singular. In these varieties,
Tá mé ag ithe ubh means "I'm eating eggs". In Standard Irish,
ubh is an irregular feminine noun of the second declension with genitive singular in
uibhe and plural (all cases)
uibheacha (but
uibhe after numberals).
Tá mé ag ithe uibhe thus means "I'm eating an egg".

I've used
Teach Yourself Irish, but only the older edition which teaches Cork dialect. I can't speak to the current edition at all.
I'm also familiar with
Learning Irish, which teaches the dialect of Cois Fhairrge (a Connacht variety). It's a solid introduction with lots of exercises.
