(BTW, the Sturm bound works for any forms, not just eigenforms, while the thing with Maeda's conjecture is really specific to eigenforms.) If that's what you had in mind, you might find it easier and quicker to work with cuspidal modular *symbols* (which are vastly quicker to compute, and which have the same Hecke eigenvalues as cusp forms).
