Welcome Tommy. The Lumia 928 is a great phone. I'm sure you'll get on well with it.
As far as guides go, you could have a look on Microsofts Windows Phone 8 getting started pages
here. They have a lot of easy to follow guides on their website. Also make sure you take a look at this thread on here called
New to Windows Phone 8-Tips and Tricks. This will give you some great tips and shortcuts.
Do you have a Windows 8 machine that you use? If so, I'd recommend logging in to your new Lumia with the same Microsoft Account. This way, any People (Contacts) you already have on your Windows 8 machine, will get automatically synced to your new phone, along with your SkyDrive and your Calendar if you use either of these as well. If you haven't got a Microsoft Account yet, you'll need to create one for use on your phone so you can purchase apps and sync your Microsoft data etc.
Enjoy your new phone
