due to the fact that I'm a real rookie, I need your help to convert the following PIC schematic to a valid Arduino (nano) schematic

Are you just trying to put together a simple LED Driver circuit using the Nano? While this is possible it might not be the best idea. You can get a 16 bit LED Driver with PWM for way cheaper.

Check this out:

and

The circuit Greg linked to can handle up to 5 Amps per channel. Can the TLC5940 do that?

nope but the MAX16818 can albeit only being 2 channels instead of 3.

After taking a better look at the schematic though you should be able to do it with a transistor circuit:

A to Vin (if your board has a 5v regulator), C to Ground, B to PWM pin. 9V supply can be substituted for a supply between 6-12V (or according to the 5V regulator specs) and can be the amperage you need to supply the LED.

You can take all the things that connect to a GPxx (General Purpose IO) pin on the PIC and simply connecte them to digitial IOs on an arduino. The characteristics of PIC vs AVR IO pins are similar enough that this shouldn't cause any problems.
