is it a good idea to go through the dependencies list download them all to ensure i have all dependencies required for lots before downloading the lots... or should i just download the dependencies as i need them???
just download what you need, some dependencies are incompatible/outdated. And the more there's in your pluginfolder the slower the game will be.
Just download them when you need them. At first, you'll have to download a lot of dependencies. But the more you download, the less dependencies you'll have to download, since you probably already have them...
