After you call the Update method, you can grab the ID by using your SPListItem variable.

For example:

int newID = 0;
SPListItemCollection listItems = mySite.Lists["Friends"].Items;
SPListItem item = listItems.Add();

item["Title"] = "Joe Smith";

item.Update();
newID = item.ID;

The general approach would be to do a search on that list for the item with the most recent creation date. The problem of course is that someone else might add something to that list in the middle of your process.

I think the best way to manipulate items is to add an event receiver to the ItemAdding event to the list where you create content. In this event method you get the ID of the item and you can manipulate it before it will be saved to the list.
