Regarding the editing software, you might want to check Hitfilm Express, base of it is free and you can buy optional modules as you wish. I recently found it, have not used it much yet but it seems ok. The full version is not expensive either.
I have used the lightworks free edition, and it is good, but the output resolution of the free subscription is not enough for me, and I do not like the subscription models as you never can be sure of the future price rises - and as I unfortunately do not have time to do this as much as I'd likeI do not want to pay for the months I will not use it at all.
If you do not do "commercial" work at all, there is also Nuke non commercial, which is a very powerful package, but for commercial use it is professionally expensive.
