No, do not put diodes directly in parallel. put a resistor and diode in series and then each in parallel.

This will work.

You can put multiple diodes directly in parallel, as long as your current limiting resistor is of the correct value.

oh yea, please excuse my PRO drawing
Yes, that will work fine. You could probably get by with a 1/2 watt resistor, as the power it needs to handle at 9V and 60mA is .54W, but I guess use a 1W to stay on the safe side.

Yes that is a parallel circuit. Components are said to be in parallel if their + leads are all connected to the same node, as well as their - leads. The other option is in series, where the + lead is connected to the - lead of another component. Parallel is the configuration you want to use in this case.

I did something very similar to this. Check the link in my sig for details.
