When I start it up cold and let it idle it stays revving 1500rpm and is really loud and rather annoying. Is there something wrong with it or does everyone's do this?

All tundra's do this, its simply the engine idling higher to warm itself up. In fact i think most vehicles do it, my old 04 F-150 and current Tundra, Sequoia and Camry do the same thing. No worries my friend.

It also might sound like a turbo spooling up, a whistling type sound, thats also totally normal for these vehicles

They all do it. It's an emission thing. I think it has something to do with getting the catalitic converters heated up quickly to reduce emissions.

They are programmed to do this to get heat into the catalysts to make them "light off" or start burning pollutants as quickly as possible.

wow. must be your first vehicle ever. even carb'd vehicles would do this when the choke was closed....and all FI cars/trucks have done it...but anyway, congrats on your obviously first vehicle. any other routine questions can be addressed via the owners manual usually. they are pretty elementary. :)

It just sounds worse than it is bcause of the engine driven fan. The fan clutch is still locked up so there is a lot of fan noise. Even when cold, I don't sit there and idle away. Just get in and drive it easy for a few miles.
