 It was clear from the I2C project that there are 2 options for the SDA and SCL lines. These are 1.0 and 1.1 or 1.5 and 1.7. But the 1.0 and 1.1 lines are also used for programming. For I2C communication, we need to have a pull-up on these pins, will this affect the programming in any way.

 Yes it will affect programming as ISSP lines does not require pull-ups. You can have a jumper to disconnect the pull-ups while programming or you can have the pull-up resistors on the I2C master device
