Anyone trying to remove conditional status on green card?

Hi,
i appreciate being able to use this site.i've got married to an US citizen & came on a temporary green card which expires in Jan 2002. now we've to jointly file i-751 to remove the conditional status on my green card .anyone in same situation please share information.
we've to furnish proofs that our marriage is genuine & for that we need to furnish at least 2 affidavits by people who know us.if we send just 3 affidavits is that enough ? what other proofs we need to show or how much is enough?we don't've any kids or joint assets except being nominee for some.
if INS thinks the proof is inadequate i may be deported from USA.
If anyone can help please write back.Thanks.
