Tomato advice

I bought 9 tomato plants yesterday. 5 Moneymaker and 4 plum tomato, not sure what kind though :o

They're currently sat in some 3" pots and are about 5" high. The Tomorite Giant Tomato Planters I bought for them say plant them in the grow bag when the first truss is set. In the meantime though, should I repot them? Or just plant them in the grow bag anyway? And what's peoples thoughts on placing bottomless pots in grow bags? Bearing in mind the "Giant Planters" are twice the depth of a standard grow bag.

 

Rod, I would be inclined to plant them up now. I don`t see the point in causing the plants stress just as they are trying to produce fruit.
