Also topping their groups ahead of more teams playing on Sunday and next week are Cameroon, Senegal, Tunisia and now South Africa.
Eto'o returned to international action to score the opener in the 42nd and the winner from the penalty spot in the 82nd in Yaounde. Dove Wome equalized for Togo, which was missing Adebayor, goalkeeper Kossi Agassa and other regulars as they continue to battle with coach Didier Six.
Senegal's draw with Angola keeps it two points ahead of the Angolans in Group J.
Tunisia kept its complete dominance of Group B intact, with Sierra Leone, Equatorial Guinea and African Cup revelation Cape Verde trailing far behind.
South Africa gave its fans a small but significant boost with a long-range goal from Thabo Matlaba and a second-half strike from Bernard Parker in a 2-0 win over Central African Republic. Bafana Bafana have gone from third to the top of Group A ahead of Ethiopia's hosting of Botswana on Sunday.
Republic of Congo's 1-0 win over Gabon was enough to keep it well clear of Burkina Faso in Group E and ensure that while powerhouses Nigeria and Ivory Coast are on course for a place in Brazil, minnows like the Congolese and Group H leader Benin also still have a chance of qualifying.
