There is no official 64bit Windows build for 1.5.x or 2.0. I think
Windows must be clever enough to use wow64 to run it in 32 bit mode.

As far as the procedure, yes it is as simple as uninstall and
reinstall, just be sure to disable the guardian service if it gets
installed.

Also, if you have manually changed the default firebird.conf cache
sizes, then you will need to choose more suitable values under classic.

If you are up to 1.8GB, then I am confident my guess at 2GB process
limit was correct. I can't see how that can be the case unless you
have a lot of databases and you have really bumped up the cache. Most
people actually get the reverse problem - a mountain of RAM they can't
convince Firebird to use.
