The main image release event will take place on July 12 at 10:30 a.m. EDT (1430 GMT).
Does NASA already have James Webb Space Telescope's 1st science photos with them?

Some of them. From the latest (June 23, 2022) NASA JWST blog post,
The team has started to take some of the first science data, getting it ready to release starting July 12, 2022, which will mark the official end of commissioning Webb and the start of routine science operations.
As of June 24, 2022, NASA has completed commissioning of 12 of the 17 instrument modes. Those commissioned modes are good-to-go. Presumably the July 12, 2022 release event will include imagery / data from all 17 modes.
