Set off of capital gains: stcg to stcl

I have a Short Term Capital Loss of 5 lakh in F&O Trading for the Financial Year 2012-13

In 13-14 I will be going to have STCG of Rs.10 Lakh from sale of an underconstruction property.

I have also paid 3 Lakh as interest on the Home loan taken for this property. No Tax exemp. claim was made bcoz it is in u/c.

My query:

1. If I carry STCL to 13-14, Can I Set off my STCL (F&O) with STCG (Property)??

2. Will Interest paid on the property will be deducted from the profit??

Pls Advise
