HI, I've designed my power supply circuit as shown below:

First, if I use 1N5392GP diode as the bridge rectifier, then can I use 1A transformer? or I need more than 1A?
Second, are the values of those components (capacitor and resistor) correct?
Third, when I use it to supply my AVR, LCD, and optocoupler, the 7805 regulator is getting hot (i dont know why). So I modify it to become like this:

I add TIP32C to 7805 regulating circuit. Well, I know by adding this transistor will provide a higher current to the load, then do I need to change my transformer and diodes (related to the current)?
Thank you..
