Two dumb newbie questions, I hope!

[jeep11]

Firstly when adding a product to the catalogue how do i get the prices to show up? Show prices is turned on in admin, is it something to do with the wholesale field needing a figure entering?? Secondly, I'm used to the previous oscmax where you just browsed and uploaded your products image and it would automatically display a clickable thumbnail through to a bigger image, in this version it appears that if you upload the image it appears full size in the admin catalogue section but just displays a non clickable image in the main catalogue section of the site? Am I missing something blindingly obvious here? Thanks in advance.

1) put the price in the right field?

2) modify the image sizes in configuration -> images -> small image height/or/width (not both)
