Right.
Other than that, do I have everything right?
When deploying the app, do I have to include an actual copy of the LGPL license (i.e. this file) or is it enough to say that this application is licensed under LGPL, and the provide a link to http://qt.nokia.com/ ?
I am not a lawyer, and beside: the LGPL is interpreted different in each country. I would ship a copy of the LGPL with my application. It has not to be in the root directory. The link to nokia is a must if you don't want to ship the sources of Qt itself with your application.

If you want to be 100% sure, ask a real lawyer. Otherwise: Nullum ius sine actione! (which means in English something like: no complaint, no redress)
