Sold Gold what's tax liability

I'm a salaried person and TDS is deducted at source. I've purchased a flat in financial year 2008-2009 and I've few queries as following:

1. I've sold gold worth Rs. 1.5 lakhs during the payment of the flat purchased. That gold was given to me by my parents during my marriage 2 years ago. What is the tax liability? If yes under what section of ITR it will be included?

2. I received Rs. 1 Lakh from my NRI friend through western union for payment of the flat. What's is the tax liability for this?

3. I had also got money from my parents through cheque/DD. Is there need to show this in ITR?

 Please answer my all queries above individually. Thanks in advance.
