The tracks - I can't really recommend them. The track lengths (they're link 'n length style) seem to have the mould stub attached to the side which was then crudely cut off at the factory. This not only means some fairly extensive clean up, it also means that all track pin detail on one side of the track runs is either in bad shape or completely obliterated. Don't mind doing some clean up, but I kinda draw the line at having to break out the punch 'n die and having to completely redo the track detail. That's not to mention there were also quite a lot of air bubbles in the resin - I'd expect more from a company with AA's image.
As Kevin's post already indicates they can be a handful to fit too. This is a result of the fact that AA don't provide nearly enough individual tracks to fit around the drive sprocket and idler wheel which means you have to form some of the link 'n length pieces to shape by immersing them into hot water (That's the trick Kevin - imerse them into some fairly hot water and then force them into position and keep 'em there while they cool off. They'll then retain the correct shape). I pulled it off, but after lots of frustration which could have been easily avoided if AA had provided a couple more individual links?
Anyway, you get the picture, look into some of the alternatives already mentioned by other posters first.
As for the detail set, a bit of a mixed bag. While some of the parts provided are definitely an improvement overall I felt most of the PE provided was a bit crude and somewhat overscale while in contrast some of the resin bits were definitely underscale. Casting quality was lacking here and there as well. I used what parts I could but still wound up tossing quite a lot in favour of Eduard parts or modified kit parts. Like I said this set will definitely add a couple of improvements to your kit but whether or not it is worth the money I'll leave up to you.
The Eduard set - get it! well worth the money and definitely worth adding to the kit.
One worth of advice though. I've been through the Trumpeter kit and even if you throw every detail set you mentioned at it 't still be lacking without lots more work. And that's not even mentioning the extremely poor fit. Why not get the Tamiya kit, buy the Eduard set for it and use the non-uparmoured parts from the Trumpeter kit to convert the Tamiya? Looks like you're willing to spend some money on this one so I see no reason not to start from the superior base kit.
I'll see if I can't take some pics of my finished, as yet unpainted model tomorrow to give you an idea of some of the work involved. If I hadn't already put a lot of effort into it before the Tamiya kit came out I would have never bothered stuck with it!
Edit : here's some pics I just found of the beast somewhat earlier down the construction line :
