Yeah, I'm familiar with the contribution limits. I'm a graduate student right now so I can't afford to make any contributions at the moment, but once I graduate and my job starts, I'll be able to fully fund my IRA(s) for both '08 and '09, which is the plan. I know I can do this thing, I'm just wondering if it's a sound bit of strategery.
it's not a bad idea, but i don't think you should bother. you seem to have a pretty good handle on these things, so i'm not going to go into a lot of detail. feel free to ask me to expand.
1) the practical point - it's unlikely that you can do the bracket math accurately enough until after the year end. you'd lose some benefit by not contributing the max as soon as possible, but this is a small point as long as you don't mind waiting. just know that there's not much point in following through with this plan unless you do wait.
2) the Roth rules effectively allow you to shelter more gains because the contribution limits for Roth and traditional are the same. in other words, for a Roth contribution you use post-tax money and for traditional pre-tax money. $1500 of post tax money is more than $1500 of pre tax money. the various roth vs. traditional calculators on the web take this into account by assuming that you will invest the taxes paid on the roth contribution money. that investment is fully taxable though. 25% is still a pretty low rate, so i think this aspect probably is enough on its own.
3) notwithstanding the above, there are good reasons to have a source of "traditional" and roth money available at retirement. if you are thinking of brackets and rates now, you should be able to understand this easily. you can pull first from taxable accounts (perhaps a pension plus your "traditional" funds) until you hit the maximum tax rate that you want to pay (say, for example, 28% and whatever dollar amount that means) and then pull from Roth funds. if you think about it, it is a complete waste to pull from Roth funds for the first $20,000 or so, which would be tax free in any event.
