Early bird needs application advice

Hi,

I have finished my sophomore year at a top-ranked US public school as a double major (Electrical Engineering with Finance) and have a 3.65 GPA. I've been shadowing the forums for a while now and though I still have a while before MBA applications, I felt it's never to early to start working in the right direction - so I'm on here for advice! Again, I'm not looking for a "recipe" on how to get into HBS (dream: to get into the 2+2 program) or any other top program (after working a few years i.e.) - but more of a "you're completely off-track/you're on the right track but doing this or focusing on this would be good" been-there-done-that advice!

So here's my current profile (after two years of college):

GPA: Slightly over 3.65 (average for the engg school is sub-3.0 but I still think it's low for 2+2)
GMAT: Haven't taken it yet - but if it's an indicator of anything, I had a 2290 on the SAT
School: Large, Public (consistently top 2-3 in the US)

Other factoids:

* Interned at a major entertainment company (Fortune 500) last summer in their new technologies department. Did a project on my own and was called back this year. It was a great summer and got a good recommendation letter out of it too!

* Interning at the research lab of a Fortune 500: Top 50 company (technology) this summer.

* Started and currently president of an on-campus business student organization. Club grew from nothing to over 60 members in less than 6 months. Is now a prominent business club on campus.

* Vice-President of an engineering society on campus and treasurer of another one

* Been on two major engineering research teams and contributed significantly. Might get a great recommendation out of one of them! Continuing one of the projects and taking a role as a research assistant on a public economics project this coming year.

* Taking the CFA Level 1 either this December or next summer (I don't know if this affects anything)

* Won a bunch of national olympiads at high school level and am currently learning French as a fourth language. (Again, I don't know if this affects anything)

* Am an international student and spent four years in another country (other than my home country) before coming to the US

* Heavily involved with a community service group for autistic children and we're planning an international community service trip for this December.

Since I'm doing a double major, I will probably take 4.5 years to graduate - so I have two years before I apply for the 2+2 and several more before I apply for regular admissions. I would really appreciate any advice, suggestions, comments - anything, really!

In terms of what I want to do in the future, I am very interested in management consulting and large public enterprises. More than that, I want to do something that makes a difference (but then again, who doesn't!) Thanks for reading this long post and for your comments!

PS: Right now, my focus is HBS 2+2, but other schools I am interested in (after working for a few years) are Stanford, Wharton, Chicago, Kellogg, Duke, UVA. Though this is probably going to change considering I have a few years left!
