For notes and todos I'd recommend "simple notepad"
Mort player for music, quickpic for images, tally-ho for a counter, bubble leveler for level (Antoine Vianey) , LED light (picolyl),
"Third" for RPG dice. For playing: jigsaroid, andors trail & vector pinball. Still searching for a free & adfree compass since "orienteer" doesn't work with ICS
SiMi clock for a minimal clock calendar weather and battery widget, SiMi folder for shortcuts to apps, folders & contacts (without pics!) "simple audio recorder" (pgsoftware)" Barcode scanner (zxing)" air droid.
