Breadmakers seem to recommend putting in different ingredients in a certain order, so I'd stick with the order instructions that came with your machine.

We do our bread from scratch (recipes did come with the breadmaker). I've found extra yeast makes it fluffier. We also use a mixture of white bakers flour and organic wholemeal flour with a high protein content, rather than a premix. We have fiddled with the quantities of each to give what looks like a wholemeal loaf (compared to shop bought), but is still fluffy enough. Wholemeal flour tends to make a denser loaf in our machine.

GL!
