Depends on what the rest of your application looks like. To help you get a more tangible sense of where you stand, in 2005, I got into the PhD program at UC Irvine with a TAship with this kind of application (I declined, by the way):
- Undergrad institution: UC Irvine
- GRE: High 700s for both Q and V, 5.0 on W
- mGRE: Mid 500s
- GPA: 3.57
- No research (unless you count 2 independent study courses)
- No publications
- Good recs from one well-known, two not-so-well-known profs
- Pretty bad statement of purpose (didn't really know what I wanted to study)
I think what might help you at this point is to:
1) Start on a research project ASAP with a prof that knows you well
2) Pick a more-or-less specific topic of study for grad school ("pure math" is too broad; "probability" is better; "stochastic PDE" is best)
3) Write a really good statement of purpose - ask profs and TAs to read your drafts and give you honest feedback
4) Find profs at the schools you're applying to whose research interests you and ask them thoughtful questions about their work via email or phone AFTER you've read some of their publications. In some cases, this could go a long way in helping your app get into the "maybe" or "yes" pile because some profs may advocate for you if they think you're capable of good research.
Hope that helps!
