Safely tossing caches? preferences?

[Bandita]

Hi, All.

Here's my specs:
Machine Model: Power Mac G4 (AGP graphics)
CPU Type: PowerPC G4 (2.9)
Number Of CPUs: 1
CPU Speed: 400 MHz
L2 Cache (per CPU): 1 MB
Memory: 320 MB
Bus Speed: 100 MHz
Boot ROM Version: 4.2.8f1

My disk is nearly full and I get warnings all the time, stuff has stopped working, like my printer! I've dumped all the apps I don't use and looked about for what's taking up all the space. About 1.5 G is going to caches! But which can be safely trashed?

How about preferences?

Disk Utility says my disk is OK. But I can't run fsck, or applejack, or macjanitor, or or or. Also, suddenly it says my user account is read only, which I can't possible trace, or even where I saw that message, and have no idea whether it should be fixed. I'm the only one using my machine.

What I'm trying to do, being tightly budgeted, is avoid a new external hard drive. But if I have to go that route, any advice?

Thanks. You guys are great.

Oops, sorry. I'm running 10.3.9. More than 9G used on 9.5G disk. Grrr.

Unless Apple is doing something really stupid, caches should be safe to trash.
About the read-only user account, run disk utility to "fix permissions" on the disk, it seems to help often enough to try out most times there's a problem.
