New 2 me car w/ small issues

[BuickPkAve]

I'm new to PA's, and this car I just got has a few issues.

The radio ate tapes so I installed another OEM unit and it all works but the AM band does not have good sound..... (didn't before either) it is weak and scratchy... like a bad antenna.... FM works great. Any ideas as to what could be going on? what is the routing for the antenna? Where is the antenna?

I need new shocks all around. What do you folks recommend?

The low tire pressure message is on. I have 36 in the front and 34 in the rear, and it is still on. What makes it go off? What tire pressure do you recommend? OK I found the button for this.

Is there a adobie version of the owners manual available?

What about a Maintenance & Repair CD?

Thanks,
BPA
