Hi, I am now 29, and I have $4000 at S&P 500 index fund,
$3000 at extended market index fund (track Wilshire 4500 index)
, and $3000 at international fund. Now, I am preparing to open
an Roth IRA account, however since I already have my asset
allocation setting up nicely, I really have no idea where I should
invest my $2000 to put in Roth IRA. I also think there is no way
for me to transfer all this $10000 in funds into Roth IRA without
any selling, right? (If I can, I would be so glad to do it ^_^)

The situation is, I've already done my asset allocation and
retirement investments on those three funds, and they are all
on taxable account, And, I don't have a mortage to pay, no car
payments, but I do have a student loan to pay out in 3 years.
Don't have wife and kids also, so it becomes totally blank
in my mind to invest which sector or funds for $2000 every year
in Roth IRA. Any ideas and suggestions? Really appreciated^_^
