For problem #2, you can leave your answer
in terms of L_o and M_o (solar luminosity
and mass) -- you don't have to put it into
J/s and kg.

For problem #3, you need to use temperature in Kelvins
to make these equations work out. 0 C is equal to 273 K,
and 1 degree C is equal to 1 K. The Sun's temperature
is about 5700 K and its radius is about
700,000 km.
