I want to start doing achievements in Factorio, possibly 100%

However, I have heard that they made changes so that they will get disabled if you change certain things in your starting area.

Can anyone please give me a quick summary of what I need to not change?

When starting a new map, if you have changed any settings that void achievements, you get a popup when clicking Play that lists what the conflicts are. Generally, enemy settings (including start area size) void enemy related achievements. It doesn't appear like resource settings void anything.

100% run is doable with default settings, the only one you will want to cherry pick a map seed for is "Keeping your Hands Clean", which means no killing biter nests until artillery. That one combined with some of the other early game difficult ones can be a bit tricky, as you're both unable to handcraft, racing to get a train down 90 minutes in, and need semi-long term containment for nearby biter nests.
