I did my first full PayPal integration the other day. Read the PayPal web standard guide, and IPN guide. These documents both answered most of my questions. Those not covered there could be found reading the PayPal forum.

If you have a specific code problem, you could post it here, and people would be able to help. But asking how to integrate PayPal is rather a broad question, wouldn't you say??
