Everyone has their own way of doing this, so you will probably get plenty of good suggestions.
The method that works for me is to do mini-biographies for each direct ancestor:
Name, BMD data, spouse, parents, children.
Images and details of all sources
Photos (if any)
Wills or other documents (if any)
Newspaper articles (if any)
Description of what their occupation and daily life involved
Views of where they lived
Family stories/memories
Depending on the amount of information, this could range from half a page to several pages!
This keeps the basic tree uncluttered.
I find it more useful to organise lines by surname, starting with the earliest known ancestor and listing them forward in time until the surname changes (on marriage).
Hope this helps
