lm358 is a dual op-amp, similar to the tl072 (I have to check if it's a pin-to-pin replacement).
lm380 is a 2.5 Watt audio power amplifier.
lm348 is a quad op-amp, and each stage is similar to a 741.
You can download datasheet at http://www.national.com perform a search there.
Depending on how many you have, one application for the LM380 is for a headphone distribution amp. You might also consider making your own 5.1 home theater speaker system on the cheap.
LM380's can also be used in bridged mode to produce higher output power amps. They can also be used as a driver section for a spring reverb (although a bit heavy-handed in that regard).
As far as I know, the LM358 is a reasonable sub for the TL022, in that it is a lowpower dual op-amp without anything particularly inspîring in the way of audio properties. You will note that it is used in the LFO of the Small Clone, and that the TL022 is often used in LFOs of other commercial modulation pedals.
