Retirement tax questions

QUICK Followup: I'm 65 and made both SEP IRA and TRAD IRA contributions this year to existing accounts. They both now say "LONG TERM" ... which technically they are. But I just made the new contributions. Can I take out any amount I wish, knowing I'll be taxed as income, going forward? I could use some of the money that is just sitting in the money market right now that hasn't been allocated to any funds.
