I need to paint walls, ceilings, bannister and spindles. There may also be hardwood window frames to add to this, dependent on the outcome of my thread in Home Decoration. 
We have a couple of cracks that have reappeared after being filled by professional decorator, do I need to do something different this time than the standard polyfilla?
Do you have to rub down the entire wall, or just dinks and bumps? I've only ever done the 'chuck paint on' type of decorating before, but want a better quality job this time.
What do you do with wood that has previously been varnished? Is it better to just replace the varnished skirting boards as they're cheap? I'm thinking they get more of a battering than other woodwork because of hoovering so the paint job need to be really good.
