Help with two input specs of a DC-DC converter

Regarding this DC-DC converter datasheet the input specs are given as:

enter image description here

Mine is 12V to 5V DC and called MV 1205S. So my input voltage is regulated 12V DC.

I have couple of issues with this part:

  1. I want to obtain a reverse voltage protection for this converter input by using a 1N4148 because that is the only diode I have. I also have 1N5408 but it has 1.2V voltage drop.

    But do I really need that? Because the input specs mentions about reverse voltage protection as 0.3A max. What does that mean?

  2. Can I use 3.3uF at the input safely? It says 1uF or 3.3uF but there is an asterisk(*) so I'm not sure if it would have any complications.
