Oooh yay, a nappy advice thread
Ok, personally I prefer 2-part nappies (where you use a fitted nappy and a waterproof wrap). I find them more reliable than pockets.
If you don't have a tumble drier then you should avoid bamboo nappies as they take a long time to dry. I also find hemp slow to dry too. So if i was you I'd stick to cotton or microfibre.
Microfibre nappies like fluffles and bambinex teddies will dry really quickly (though they aren't natural fibres). It would be handy to have a couple.
I'd also suggest you had a few bamboo nappies for overnight as they are more absorbant then any others IME. (number you'd need would depend on how often you'll wash them)
For the cheap-ish option I'd suggest using muslin squares or terry squares when your baby is first born, there's many folds you can use and you can fasten them with nappy nippas. Then I'd go on to a size 2 nappy (some of these can be folded over when the baby is small and they still work well or you could have a look at birth to potty nappies, tho they can be complicated at first)
For wraps I'd recommend the motherease rikki and airflow wraps (not the prettiest but by far the best)
As for how I wash etc. Depends really, sometimes I dry pail the nappies (basically chuck them in a nappy bucket then into the washer, do a rinse cycle then a proper wash at 40. Other times I wet pail then just do A WASH. (oops sorry for caps)
\have to admit i tend to use the tumble drier at the mo, line dry in summer.
I use fleece liner (buy a cheap fleece blanket e.g. from ikea and chop it to the size of the inside of the nappies iyswim)
Also use washable wipes (chopped up towels) with a spray bottle containing cooled camomile tea.
