Don't want to give too much away either but I agree with your review.
There are three augs you want right away. The arm strength aug to break through walls, the leg augment to jump to higher points and the one that modifies your vision so you can see through objects and have important objects like palm readers, items, etc highlighted. Both of these are useful from the very start of the game. Don't forget that the environment can be used in ways you might not think of. Dumpsters can be moved to give you a higher point from which to make a tough leap and they often hide access to vents.
