Pillar and skim bed action to stock
For all three of these items, you can search this site and youtube and find great how-to's.
You're right that recrowning a barrel would require some machining. When it comes to bedding, do not bed a cheap stock (like the synthetic stock that most Remingtons come with).

As for reloading, it sounds (I think) that you have the necessary gear (hand press, dies, powder scale, calipers, priming tool etc)
As for your components, a few comments...
RL17 - good powder but temperature sensitive. Consider H4350.
130grain bullets - this is the classic bullet weight for the 270. As the ranges get longer consider the heavier bullets. With a 1:10 twist barrel you can shoot up to 150grain bullets.
Heavier bullets - if you go to 140 and 150grain bullets, consider a slower powder like H4831
Chronograph - definitely get a chrono. Shooting without one is like shooting with your eyes closed. Even an inexpensive one is better than none. Shooting Chrony F1 Chronograph
