A JS140 is a solid guitar. It wouldn't be my first choice for a beginner simply because of the tremolo. I feel like those completely new to guitar are better served with a fixed bridge guitar just because it's a simpler design. A tremolo adds some complexity to the system and my fear is twofold: 1) that a beginner might spend time futzing with the trem that would be more productive learning the basics, and 2) that the nuances of tuning and maintaining a tremolo may be frustrating. That said, it's a very sexy guitar and just the appeal of playing like your guitar hero(es) is probably enough to offset any downsides of the added complexity. I would suggest at least removing the tremolo arm at the beginning to allow you to focus more on the basics.
In terms of learning, there are SO many resources out there. I would suggest starting with YouTube videos, simply because the cost is minimal (a few seconds of your time spent watching commercials). One channel I find quite good for beginners especially is Justin Guitar. I find Justin to offer great instruction and you'll find a decent variety of songs. But there are TONs of other similar YouTube instructors out there and I'm confident at least one of them has a teaching style that will work for you. Just search almost any song you want to play on YouTube and add "guitar" or "play-through" or "tutorial" and you'll usually find at least one hit.
Once you've got a few simple songs under your belt, you'll want to learn to read tablature and chord diagrams. Once you have that down you can search Google or Ultimate Guitar and find tabs for just about any song you can think of.
You will probably come to a point sooner or later where live instruction will be very beneficial to move your skills along, but the Internet is a great place to get started in learning.
