For the most part, yes, you can use the 115 JHP data. Treat it as a starting point. The biggest issue is the OAL. You will need to ensure that you err to the longish side of the spec. Also, if you are using a name brand bullet, call the manufacturers customer service line and see if they can help. Another way is with the "Plunk test" on your particular pistol.
While I use Unique w/ 9 mm, I primarily use it for 147gr bullets. For the lighter practice loads, I like Bullseye.
You will want to accumulate some more loading data as you go forward. I have three manuals along with all of the electronic data I can find. The Lee Modern reloading 2nd edition is worthwhile. It's a compilation of a lot of different data. I also use the Lyman 49th, it is a very good manual overall, but as you noticed, it does have some odd gaps in coverage.
