For aluminum seatposts, I like Thomson. There are both setback and non-setback models (setback is typical for road geometries) and they're 2-bolt "infinitely adjustable" clamps, though at the cost of weight. There are lots of carbon posts on the market, and they've fixed the breakage and slippage problems that they were having 2-3 years ago.
Saddle choice is very personal. If the intended rider doesn't have a preference, Terry has a reputable women's-specific line.
