Career Dilemma - Completed a guide

So a little bit of background information - I completed a summer internship in IB with a BB and a year with a boutique before it imploded. This was sometime in September last year. Since then, I have found a position in Asset Mgmt, and have been working there for around a few months or so.

Here comes the problem. I do not enjoy my current position at all. I don't like the people I'm working with, and the type of work is extremely unappealing to me (lots of writing, generating reports, building Access, yes Access, models). It pays well, the hours are good and I suppose there's a learning opportunity in there. However, I go to work everyday thinking about leaving and find myself pretty unhappy.

So the questions being,

1) Is there a chance I could go back into IB, considering I have been out of it for 5-6 months now, and was only at a no-name boutique?

2) How bad would it be to just leave my current position after only a few months - I suppose I shouldn't even include in my resume?

3) Should I stick it out for 2.5 years (bringing total FT work exp to around 3.5 yrs), and apply to B-school then?

4) What are my chances of getting into a good B-school, assuming I get my CFA by then and the organization is well-known?

Some might wonder why I want to return to IB after escaping, and I can genuinely say that I do miss a whole bunch of stuff about it, even building those late-night comps. Weird I know.

Any advice is appreciated. Please be honest.
