Extension Visitor visa - is any of these valid ?

Known Information:
Visitor visa - Multiple entry valid for 10 years (till 2012)
I-94 - expires on Mar 30 2004
Application for extension-- Feb 10 2004 (assumption)


Which of these assumptions right / wrong ? Pleae help me

1) a person can stay past the i-94 expiration date, IF they have just-applied for visitor-visa-extension before March 30 2004 ?

2) a person can stay ONLY IF they get a receipt from INS for an extension-application ?

3) If extension-application is denied, a person will be out-of-status that hour that day that time ?

4) If extension-application is denied, a person should leave the usa immediately ( within 10 days is just an assumption)

5) If extension-application is denied, even if a person stays more than a single-day, they are treated as OUT-OF-STATUS, and their 10-yr-mul-entry-visa is INVALIDATED right away automatically ?

6) If extension-application is denied, and if person leaves USA 1week from the date-of-denial-letter, person will be questioned/grilled at Departure by INS ?

7) If extension-application is denied, and if person overstayed for 1 week, if they plan to visit USA next time, they have to APPLY FOR A NEW VISA at their home-country ? (even though they had a 10-yr-Mul-entry-visa)

8) If extension-application is denied, and if person overstayed for 1 week from the receipt of denial-letter, AND if they plan to visit USA next time, they cannot PLAN a trip atleast for a GOOD 1 YEAR period ?

9) If extension-application is denied, and if person overstayed for 1 week from the receipt of denial-letter, they will be BARRED to enter USA for 5 years ?

10) if persons exits usa before i-94 expiration, with extension-pending, can they come-back & enter usa in 1 week or 1 month ? Will they be questioned in POE about their intentions of coming-back immediately in a week's time or month ?

Iam confused about this whole visa-extension-procedures ? Please help
