If you have ANSYS setup installed, then in the HELP tab of fluent you will find the Fluent theory guide, user manual and tutorials. Tutorials are available in tutorial manual. The mesh files will be available in the path specified in tutorials. You can import those files in fluent and setup a case. Also, in ANSYS workbench, you can use workbench meshing or ICEM CFD for meshing.
If you have a FLUENT customer number, make an account at ansys.com for full access to all documentation. However, that's mostly useful for theory behind the models available in FLUENT.
If you want to get started with Finite volume CFD in general (not FLUENT specific), I like the book by Versteeg and Malalasekara as a starter. Bit old maybe, but covers all the important basics.
Furthermore, the website of Andre bakker (bakker.org) covers some lectures on basic CFD, with FLUENT as the used software. The tutorials of Cornell university (google FLUENT Cornell and you should find them) offer a very detailed "getting started"guide, from geometry to validation.
