Actually, you don't even need a new spring; that's a common part between the Remington +2 & +3 extensions.
The Remington extensions are good kits, but the problem for a highly-configurable setup is that they're fairly involved to install and remove because they consist of several parts, and require that you at least have a screwdriver handy. Also, since they require a bracket to stay in place, they can be picky about barrels. Odds are at least some of the barrels you end up getting won't play nice with the Remington extension bracket (especially the slug barrel, as those often have heavy outer profiles).
Since I also use one receiver and a number of barrels for all my shotgun shooting activities, I've drifted to single-piece extensions because they make everything so much more straightforward. The Wilson Combat kits are a great bang for the buck, but they are only offered in +2 and +1 lengths. You could stick with the Remington +3 tube for when you want that capacity, but be aware that the WC and Remington extensions are intended to use different magazine follower & spring styles (tailed follower & beehive spring for the former, straight spring & cup follower for the latter). Each should run well enough with the other's spring & follower, but you'll see a loss in magazine capacity with the Wilson, and more sluggish spring function in the Remington.
Really, of the three extensions you mention, it sounds like the one you'd use the most would be a +1. It's what'll match your 14" barrel, and the 12" barrel is going to end right at a magazine cap. Then, both the 26" and 23" rifled barrels are for hunting/sporting applications where more than 4+1 shots doesn't do much more than make the gun heavier (though perhaps you like an extended magazine for sporting clays?).
I will say though, having done a fair bit of slug shooting, a steel single-piece +1 can be a nice thing to have installed so that you can load a full box into your magazine rather than keeping one odd shell in the chamber or your pocket; and to add a little extra weight and a place to clamp on accessories. Remind me to post a picture of the short-barreled slug setup I'm trying out with my 870.

For chokes, if you have the money, I would reccomend extended chokes simply because the extended knurled ends make them easy to install, tighten, and remove without using a choke wrench; and the extended portion provides room for easy-to-read labels, in case you forget which tube you have in a partictular barrel.
Just for those reasons (I've never felt that my other flush chokes were ever to blame for my misses), the last several chokes I've purchased have been extended ones. No porting or other gimmicks, just plain extended. As for constrictions, a set of Full, Modified, IC, and Cylinder tubes will let you do almost anything. You do already have a Cylinder tube in your breacher choke, but a normal Cylinder choke tube will give the same patterning (or possibly better, as the ports on the breacher choke have been known to mess with some wads) without the extra weight and length when you want your gun to be practical rather than tacti-cool.

out shooting sporting clays with 870 and 11/87. Believe it or not the 11/87 was eating the cheap Wal-Mart Federal Premium low brass target and field loads. We shoot about 400 clays each. It was a long day
