You can usually find that information in a Haynes or Chiltons manual, which you can usually buy from auto parts stores (Autozone, Advance Auto, etc), though each store usually only carries one of those brands. You can of course buy them online, too.

If you need the actual factory service manual, I believe there is a website that allows you to pay for X days of access to the factory manuals for various models. The alternative is to buy the physical copies of the service manual, but those can be very expensive. My 06 has 3 giant volumes, but you can sometimes find these cheap on eBay, which I've been doing. I'm old school enough that I prefer the physical manuals, partly because they are fun to browse, and I've learned a lot this way. But you only need these if for some reason the Haynes/Chiltons manual has omitted a torque spec, which does sometimes happen (really pisses me off), or you're trying to rebuild a power steering pump/rack, etc.

Alternatively, you can sometimes get lucky and find a pdf from a sketchy website. I found the 04 manual this way, but it's only occasionally useful for my 06. YMMV.

EDIT: The Haynes and Chiltons manuals are the economical option, and they are good for 90% of what most people need. However, they like to put torque specs at the front of the chapter, and sometimes the descriptions are not super clear. I think I started going cross-eyed on the suspension specs for my car. What is nice about the factory manual is that the torque spec is very clearly labeled. But again, most of the time it can be figured out. $25 vs $250, your choice (somebody can probably weigh in on that website for X days of access though, I think it's probably the comfortable middle-ground)

The dealership and ebay! Did you try google I found mine in less than a second. Google is easier to use than a card catalog at the library. Especially if your willing to actually pay for them instead of trying to get them free. You can get them in actual book form and electronically. If looking for it for free you will want to try searching Russian sites!

I have published torque spec. for specific things from my owners manual in the past and most importantly the pages that are in the Toyota Service Manual that list torque spec by fastener size as well so you do not always need to be looking at the specific instructions. You can print those laminate them and stick them on the side of your tool box with some hot glue and rare earth magnets!

 

The service manual will not be engine specific that would a moronic thing to do. It will have both engine specific details listed. The suspension parts will not have a different torque spec based on engine again that would be beyond stupid. The Service Manual will be specific to those model years that used the same platform so all XV30 Camry's will have specific manual separate from XV40 and so on. Usually Service manuals run $150 to $300 each with 2 or 3 manuals per vehicle and then detailed wiring diagrams and detailed transmission rebuild manuals are sold separately.

You should be able to use google though and get the answer you need unless you do not know how to use google.
