Progressive disclosure is a great idea fraught with implementation issues.
For starters, you usually need client side scripting to do it, which reduces its accessibility. The other big problem is what you've touched on - user attention. On the one hand, you need to avoid people missing the 'new' questions but on the other hand you might have users being 'surprised'. One way to overcome all these problems is to use pagination. If you ask 'set up' questions on your first screen, you can then provide the appropriate (conditional) questions on the next and later screens. No scripting needed, no surprises, no chance of missing relevant questions. One of the main /disadvantages/ of this approach is that the form may not lend itself neatly to pagination. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
