If you're looking to improve/get into making pixel art, Derek Yu's  tutorial is a good starting point. The Dream Diary Jam blog has a few resources for RPG Maker specifically under the Graphics heading. pixelprospector and Pixel Joint  have some tutorials for pixel art (pixelprospector has quite a few on general animation and drawing for games too!).

As far as programs go, there's a few free ones like GIMP, GraphicsGale and Piskel that you can do pixel art in. There's also Photoshop and Asesprite, though those'll cost money to use. Hope that helps!
