I have a Motorola E398 on the Vodafone network and I need help on which flash card I need is it an SD, microSD or something else?
Also am I able to get these in DSE or from an online place like ascent.co.nz
It definately looks like the right size to me. Not sure why you were having issues regarding MicroSD being too small.
If you're located in Wellington, try taking a trip out to the Lyall Bay DSE. They've got the best Technical experience of any retailer I've come across and they'll be pretty willing to help you test out a card and get it working for you.
