Self assessment tax

By the end of 31st March 2009 I had 12769 total tax due for AY 2009-2010. Out of which 1000 was paid in Dec and 1500 was paid in Feb as TDS. Now I'm left with 10269 as self assessment tax.

How can I pay self assessment tax (Which Chalan/Form) and how can I calculate the penality for late tax if I have to pay by end of April 2009?
