The returns will allow captain Mellissa Berry to move back to her more usual position of no 8 after filling in nicely in the centre, and for Rachel Taylor to return to lock after performing well at no 8.
Laura Prosser retains her place at scrum half, while Rhian Bowden, who came off the bench to make her return after injury against Scotland, starts at hooker for the first time in this campaign.
Wales Women head coach Jason Lewis said, "Naomi Thomas is one of the most naturally gifted footballers in the women's game and it's great to have her back along with Clare Flowers. Ceri Redman did excellently in our first two games after making her international debut against England which is great for our strength in depth in that area.
"This is a crucial game for us, there's no doubt about it. If we beat France we have a really good chance of finishing within the top two for the third consecutive season which would be a real achievement.
"Losing in France last season is something that still hurts. We had beaten them earlier in the season at the European Championships and we were guilty of underestimating them in the Six Nations. We certainly won't make the same mistake again and we'll have to be on the button both in attack and defence if we are to answer the questions France will ask of us. They will be a much tougher proposition than Scotland, although they lost to the Scots on the opening weekend."
