Ok, I am a LC newbie. Have had if for about a week and love it, but I need some input from the experienced members out there.

Has 91,000 miles and is in really good shape. As far as tune up, what things should I (must I) do? I am planning on:
- Oil and oil filter change
- Tranny oil and filter change
- Diff oil change
- PCV change (and grommet)
- spark plug change

What about:
- plug wires?
- EGR valve and other stuff?
- O2 sensor(s)?
- shocks? What kind brand for mainly road driving with occasional offroad?
- steering stabilizer? (how long does this last?)
- timing belt/chain?
- ????? (anything else?)

What things should I look for/plan for?

Then there is the dang stereo stuff. Want to put better stereo and speakers in, but everyplace seems to laugh at me because of the setup. What can I do? Anybody been successful? What did you do and what did you use?

Finally, how about alarms? It looks like an aftermarket alarm was added and then removed before I got the LC. But I got NO remotes of any sort. So I guess the factory stuff is ok, but I am not sure. Doors lock and unlock as they should with the key. What alarm would you recommend? Remote start??

Thanks in advance from an LC newbie. Hopefully the newbie part will change REALLY soon!!
