Green Card Question

[rpurush111]

My second term of H1B visa is expiring on July 2008. I'm planning to change my job in May 2007 and will be applying for my Green Card later this year (2007). What is the latest date that I need to apply for my Green card so that I will not be in danger of expelled from USA? Also what green card stage should I need to be in, so that my H1B visa can be extended, and for how many years will my H1B visa be extended?

Thanks in Advance!
