Not sure anyone will see this since the post is rather old now and off the front page, but just to add my two cents: I was made an offer for L5 at Amazon earlier this year. For compensation, it's like you suggested: the offer is structured such that the first two years weigh more heavily toward cash (a separate signing bonus for each of the first two years, which IMO was pretty good and _does not_ need to be paid back, it's just combined with your normal bi-weekly paychecks) and then the latter two years are where you get the majority of your RSU rewards, which wind up being worth the same or more than the cash bonuses of the first two years (assuming I suppose that the stock price continues to be stable and/or increase from what it was at time of signing). A note about the signing bonuses, the offer letter details basically do not say anything about needing to pay them back for leaving early. If your employment is terminated (by yourself or Amazon itself), then you just end with the prorated portion for the current pay cycle and that's it, you don't get any more of it (fairly obvious anyway if you leave a place).
