Thoughts about TFA story/plot

Before I start let me say something first please. This is my first post on here so I'm sure everyone has his/her thoughts/opinions on the story of The Force Awakes. I wouldn't be surprised if some people thing the same as I do or some of the things I do. I'm just putting this out there because I wanted to talk about it to someone

So here's my thoughts on the basic overview of how The Force Awakes will go.

Act 1 is all set on Jakku. You're introduced to Rey and Finn they end up meeting near the beginning of the film. Rey finds Anikin's lightsaber (the one Luke had in 4 and 5) in the wreckage of the fallen Star Destroyer. Max Von Sydow's character somehow came across it and kept it as a trophy, souvenir, whatever and contacts The First Order. That's how Finn shows up in the movie, he's on the ship that shows up. Han and Chewie overhear the conversation between Rey and Max Von Sydow, they intervene; come across Finn and they return to the Falcon just in time. Finn mentions Poe Damerod being tortured on the Star Destroyer and somehow rescue him. Also during the conversation on the Falcon Han talks about the stuff that happened in the OT and probably a few tid bits that happened in that 30 year span to help people catch up. Luke is also brought up and how he hasn't been seen in a while and Han mentions he knows someone who might know where Luke is and they head that way.

Act 2 is set on whatever the planet is you seen in the trailer with Han and the others enter that multi flag building. Han introduces everyone and (I forget her name) talks about Luke, the force, more things that happened in between Jedi and Force Awakens. Eventually The First Order finds Han and the others and attacks. A fight ensures, Poe has contacted The Resistance by then and they show up right after the scene of Han, Chewie, and Fenn are shown with their hands over their heads. After the battle is over Han and Leia are reunited and say their thing. The resistance then makes their plans for the assult on the Starkiller Base (aka Sun Crusher). The scene probably resembles the same one you saw in Episode 4 on Yavin's Moon.

Act 3. Han and Chewie leave reluctantly at Leia's wish to find Luke. Rey goes with them, Finn stays behind to help The Resistance. The Resistance fights The First Order on two fronts. Air/space battle and on land. That is where Kylo Ren and Finn face each other. I'm guessing that fight ends in a draw if both are suppose to be in episode 8 like I've heard. The Resistance somehow destroys the Starkiller Base, probably similar to the Death Star battle in 4 and/or 6. Back to Han. Han, Chewie, and Rey find Luke, they all reunite and talk, and Luke explains why he's been missing for so long and agrees to train Rey to become a Jedi. End movie.

I have a few other thoughts about a couple of plot points I'd like to get anyones thoughts on. I should note also that these ideas are taken from a comment made by a Lucasfilm/Disney exec. about the Legends books not being cannon but are there to take ideas/get inspirations from.

Kylo Ren is Han and Leia's son (aka Jacen). They had a daughter as well (could be twins) but when their daughter (aka Jania) finds out that Kylo Ren is sliding towards the dark side he kills her to keep her quite. Very similar to the "Legends" books except Kylo kills his sister instead of the other way around. This death is actually what eventually drives Han and Leia apart. Neither one can handle the grief so Han leaves with Chewie by his side.

To add more sub plots to the Solo children, Luke was their teacher and after Kylo Ren fell to the dark side, Luke felt he wasn't a worthy teacher to teach anyone the ways of the force. This is why he goes into seclusion more so then any other reason.

Another plot point that gets revealed at the end is that Rey is Luke's daughter. Could be a nod to the Mara Jade character. Somehow she dies (maybe by Kylo Ren as well), and Rey was left with her grandparents, aunt, uncle, some sort of family member on Jakku.

A third character plot is that General Hux is actually Grand Moff Tarkin's grandson. I think he's too young to be Tarkin's son.

And one more idea. Andy Serkis' character has a brief but impactful sceen. He's probably got something similar to Palpatine did in Empire, talking to Kylo Ren; guiding him/giving him advice/etc.

OK so that was a lot of typing. If you've made it this far thank you for taking the time to read it and I would very much like to get your thoughts on it.
