If there's anyone who can, please let me know if the similarities between these two formulas imply a relationship between gravity and electrical attraction or hint at a unified theory, or if it's just a coincidence or a consequence of something else.
There's some relation in that they both act on fields, but the things that affect those fields are very different (higgs bosons and electrons respectively) and the relationship between all that for an 'unified theory' is a topic of much research. IANAP though (not a physicist)

Are higgs bosons supposed to be gravitons? I think you're confused about how some particles aquire some of their mass, and how all mass behaves.
