Nope, at least on the weaponry development issue for the F-22 – Aim-9X, no helmet mounted sights, and only about 2/3rds of them are combat ready ("combat coded" is apparently the term they're using for the Raptor).
"The service currently has 186 operational Raptors remaining in its inventory — of which only 123 are "combat coded" according to Air Combat Command".

Things are so dire for the F-22s, and they're spread so thin, that several squadrons at Red Flag, and/or the training center in NV have to share them. IIRC, I think it's one reduced squadron (not even a full one), being shared between three different USAF squadrons for training, and development.

"Fulfilling the operational need for air superiority fighters will be further strained in the near term because the F-22 retrofit—a mix of structural alterations to the fleet of aircraft needed for the airframe to reach its promised service life—has been forecasted to run through 2021. As a result of the retrofit, only 62 percent (103 of 166) of the active duty mission fleet of F-22As are currently available.35".

"Moreover, the Raptor's software is particularly obtuse and difficult to upgrade — which is partly why integrating the AIM-9X and AIM-120D missiles onto the aircraft has been so problematic".
You're correct on the gun issue though, now that you mention that – it is "The F-35 Coot" that is having those software issues. Supposedly, the guns have been tested and can be fired, but no one has confirmed that the software is in place and working, to enable the gun's rounds to hit their target(s) reliably.
I blame old age and lack of sleep for that mistake.
Found it – "But to field even that paltry force, the Air Force had to cut its test and training force to the bone—so much so that the elite pilots at the Air Force Weapons School at Nellis AFB, Nev., have to share their thirteen F-22s with their operational test community brethren across the ramp at the 53d Test and Evaluation Group. That means the two Nellis squadrons are sharing half-a-squadron worth of planes amongst them".

Also, from the above article – "Nor will the Raptor receive a helmet-mounted cueing system—which would allow it to take full advantage of the AIM-9X—until 2020 at the earliest. The original plan was to field the Raptor with a helmet-mounted cueing system on Day One—but a combination of a lack of funding and technical problems torpedoed that plan".
While reading about this, and others, also saw that we're now down to only 96 F-15Cs too. Perhaps not surprising when we see the design is 40+ years old. They don't seem to have the longevity of the B-52s, which many seem to think will still be in service a full century after they first flew for the country.
