I bought a used 2002 Lexus RX300 but it doesn't have any of the owners manuals. I not sure what all the extras it has or how to use them. I'm looking to buy all of the books with case.

I have read this 6 times and still not sure what the issue is? I have a 2005 ES330. To open all the doors with the key fob, you have to double press the Unlock Button. Pressing the Unlock button once, only opens the driver door.

The door lock module and further help is in the link.

Here is a link to the service manual for the RX300 just look it up. I think these bolts are torque to yield, so all the bolts must be new and not reused. http://bio.souz-96.com/Lexus/RX300_Repair_Manual/Repair%20Manual%20ENGINE%20+%20CHASSIS%20+%20BODY/Service_specifications.pdf

Your tranny need to be repaired at once. The tranny is slipping. Some Lexus owners do have the similar problem including myself.

I don't think it's a problem with the homelink opener in your RX300. Try resynching it again with the garage door opener. Mine failed to work once and I just resynched and it's been OK for months now.
