I just passed my technician and upgraded to general today.
Congratulations!
I believe that the larger ham radio dealers, such as AES and Ham Radio Outlet, periodically download the license data from the FCC so they can pick up on new licenses. My guess is that you'll receive an AES or HRO catalog in the mail within a month or two. Or, you could just go to their web sites and request a catalog.
As for magazines, I am a life member of the ARRL, so I get QST. There is usually a wide range of articles in each issue from product reviews to projects you can build to stories about on-air operations plus regular columns on technical issues, public service, contesting, DXing, etc. QST will soon be available in a digital edition that you can read on your computer or tablet.
CQ magazine is still going strong, though the technical articles are sometimes a bit weak. It's not unusual for CQ to have a product review that focuses on how to use the product in real life while merely reiterating the manufacturer's specs. The in-depth technical review will often show up few months later in QST. Nonetheless, I subscribe to CQ so I can get a different perspective on the issues facing amateur radio rather than just reading the ARRL party line in QST. CQ is available in a digital edition.
I also subscribe to CQ VHF. This is a quarterly magazine that focuses on operating above 30 MHz. If you have an interest in VHF-UHF weak signal work, satellites, VHF-UHF contesting, moonbounce, etc., then you may be interested in this magazine.
I also pick up Monitoring Times every once in a while. Their articles cover a broad range of monitoring topics from VLF beacons, through shortwave listening, AM and FM broadcast monitoring, to various types of scanning. My pet peeve with MT is that is is published by Grove Enterprises who also is a dealer of shortwave and scanner radios. It's not unusual to see a product review in MT followed by a full page ad from Grove advertising the reviewed product. Draw your own conclusions. MT is available in a digital edition.
