Collecting Silver American Eagles

I am facing a dilemma, I have just gotten back into the hobby after a couple years and I opened my album of BU silver eagles that I got a few years ago to see what I needed to finish off my collection (i have 13 out of the 22 in the series) and I noticed that some of them started to tone, I have mixed feelings about this. at the moment there just beginning to tone so they aren't the pure white anymore but there not rainbows of color either, just kinda dull around the edges. so I'm thinking about just leaving these in the album and letting them tone, and starting up a second set that will go into Intercept shield 2x2's then into a Intercept shield Box, then into a Ziploc bag with silica gel. so in the end I will have a set toning naturally and a pure white set. also where can I buy the ASE's at a good price? I see at http://www.raykomkacoins.com/ they have them for 25 a piece, I have never bought here before but I have heard good things about them. I doubt I can find them much cheaper any where else seeing as silver is 17 something an oz. but even a couple dollars cheaper each would add up fast buying a set and a half of them. I'm a college student and dont have unlimited resources but I will spend the money to do it right. this is probably my favorite coin design and I dont ever plan on selling these.

so I guess my questions in a nutshell are

intercept sheild 2x2's in a intercept sheild box in a ziploc = no toning ever, correct?

best place to buy uncirculated ASE's?

also how long does it take for the entire surface of a coin to get a nice tone being stored in and album?
