Definitely Tony Stark (if he were still alive in the fanfiction). Tony has always been a mentor to Peter. His vast knowledge and resources could be invaluable in helping Peter deal with whatever problem he has. He could create new gadgets for Peter to use in case his omega situation requires special equipment.
In a fanfiction scenario, it's also likely that he discovers a new community of omega superheroes or mutants. This new community could teach him about his omega nature, its strengths and weaknesses. They could also help him develop new skills or powers that are unique to omegas, which would then help him in his fight against evil.
One common theme is identity struggle. Peter has to balance his identity as Spider - Man with his new - found omega identity. Another theme is relationship dynamics, especially with alphas in his life.
Fanfiction.net is also a good place to look. There are a large number of Spider - Man related fanfictions there. You may need to be a bit more specific in your search by adding keywords like 'omega' and 'Peter Parker' to narrow down the results.
