Market Place Installed Apps, After Flashing

[CWasko]

Ok, so, I'm going to go off the deep-end this evening and try the revert to 2.1 and root and 2.2 flash posted on XDA the other day. I don't really have any data or paid apps on the phone, but I have installed like 20 free apps. So, when I do this event, and completely erase the phone, when I log back into the Market, will I be able to *easily* download all the apps I downloaded prior? Meaning, does it keep track at Google... or on the phone? I don't want to have to write down all the apps, go find them again, and install them. However, I don't mind clicking every list item to get them to reinstall.
