Defining "Essential" is hard, so instead I will put up those I -use- the most.
I have sorted them in 3 categories:
Combat/useful nanos(81): You should get these (or lower QLs of them)
Nice to have(74): Will give you and/or your team an easier time. Seldomly used buffs are also in this category.
Fun(16): Strange nanos that do not enhance your combat abilities, but you might want to get them anyway.
The nanos here are the highest QL Agents can use, some with a note of not being the highest, but lower QL nanos working better, for my playstyle.
Adventurer - I very seldom use this profession, I only use it for travelling/quests in SL (and for parties, with the shields (sparkles) and morphs)

Combat/useful nanos:
