... you should check out Smart Vote, where you'll find a lot of information about the candidates contesting in the three Bangalore constituencies (North, Central, South). The page for Bangalore-North, for example, summarizes each candidate's affidavits, and has links to more detailed biographical information, and to video interviews (in which each candidate answers a set of questions).
I haven't checked the availability of these resources for everyone, but they are definitely available for the four major party candidates: C.K. Jaffer Sharief (Congress), Chandre Gowda (BJP), Padmaa K. Bhat (BSP) and Surendra Babu (JD-Secular).
Another useful part of this site is the Links page, which has a lot of useful links to many institutions of governance in India.
