IF I BECOME ELIGIBLE FOR A ROLLOVER DISTRIBUTION CAN I ROLLOVER ALL SOURCES OF MONEY IN MY RETIREMENT PLAN ACCOUNT TO AN IRA, INCLUDING MY ROTH 401(K) CONTRIBUTIONS?

No.  If a Roth 401(k) account is distributed in a rollover, it can only be rolled over to a Roth IRA.  Any sources of money other than Roth 401(k) can be rolled to a regular IRA account.
