Courgettes don't grow upwards, they grow outwards, so yours is behaving normally. Leave the flowers on - the first ones will be males, on long thin stalks - then it will have female flowers, on short fat stalks that are really the future courgettes. Hopefully when it has both sorts together the boys will pollinate the girls and those short fat stalks will turn into courgettes
You can grow courgettes in pots, I've done it, but you do have to give them a very large pot - mine was about 18" across and nearly the same deep, and you have to give them a lot of water. It would be better in the ground if you can squeeze it somewhere in a garden border - they can look fantastic with those big architectural leaves and huge sunny yellow flowers .
As for the chilli, If the organic spray has cured the whitefly then with a bit of tlc the plant should be fine - but it may be a bit behind the other.
