Wharton will help you in terms of getting core finance knowledge and skills in an academic setting. There are also several extra-curricular lessons and club-type activities that can help you better familiarize yourself with finance. Of course, there is also the extensive Wharton network which you can leverage.
All that being said, my honest opinion is that you will have to do more on your own to be most competitive. These days, the VC market is not exactly hiring left and right (some might argue they never were). Oftentimes people interested in the VC area who are successful in getting jobs there have: a) a solid background in finance (e.g. - reputable i-banking experience); b) in-depth expertise/knowledge of a particular field of interest to a VC; c) extensive networks in the VC community; and/or d) readiness to spend a lot of time recruiting and networking during the school year (including sometimes doing an unpaid or low-paid "internship" during the school year).
Now, I have no idea what your specific situation is, but many from an IT consulting background tend to lack a) and c), above. They may or may not have b).
In short, the goal is great, and Wharton will get you on a great head start on your career change; you may also need to find other mechanisms in addition to further strengthen your competitiveness against a pool of colleagues and peers who may also attend Wharton with far more extensive professional finance backgrounds. This can certainly be done (and has been done). You just need to be realistic and mentally prepared. Make sure you have a fairly clear game plan; this will be critical to a good application, as well as to getting you set on the right course professionally early on.
