I have a couple of dissagreements with metalhead. Nothing major, mostly just style. Playing as an expansionist I like to build enough scouts to send one out to each point of the compass. That is 4, unless there is a coast nearby. Then 3, or even 2 if two coasts. Then I go straight for a Granary. I don't worry about an MP for quite a while - I use the slider. I am hoping to get cash and techs from huts and want to get scouts out asap. Also by not building a settler right away, I give the AI time to get ahead in cities and increase my chances of getting a settler/city from a hut.
The luxury slider thing is pretty arbitrary. I prefer to maximize my own research no matter what, and I often run at 90% science as long as is feasible, unless I get the GL, but this is just my personal play style.
If you are only building 4 scouts total, I don't think you're maximizing the potential of expansionist. To put it philosophically, building scouts is your only advantage as an expansionist civ, and the advantage quickly disappears as you approach the middle of the Ancient Age. Therefore, it makes sense to absolutely maximize this advantage by flooding the map with your scouts.
Of course, on tiny and probably even small maps, 3 or 4 scouts is plenty, but on a larger map, you will find many more huts with 8 or 10, because you can send your earliest built scouts as far away as possible while scouting your more immediate surroundings a little later. You will find yourself reaching far-away huts with much more frequency. Also, if you are limited to 3-4 scouts, it is a much bigger blow if one gets whacked by a barb. The whole point of scouting is to cover as much of the map as possible in the shortest amount of time, and the best way to do this is with an exorbitant amount of scouts.
Relying on popped settlers/cities by not building your own and allowing the AI to pull ahead is a very good strategy. However, on Emperor/Deity, this happens automatically, so you can build your own settlers as fast as possible and still get a couple free from huts.
The bottom line is, if your style is working for you, go with it. But I played expansionist civs exclusively for the first 3 months I had the game, and found that as far as scouts go, the more the better. Give it a go, you'll be happy with the results.
