Need help developing Virtuemart mod. for custom products

[ingmaniac]

Hello!

I would like to modify VM that i can create products with custom attributes such as length and heigth.
The price of the product should be given by a DB-table.

I would programm that on my own, but i'am late in time, so i would need someone who can tell me where to look for in the code.
It would be great if someone could tell me Where the html output of the attributes is done, where the prices get calculated and where the delivery is calculated.
Because delivery is an issue, shipping is expensive when length is grater than x.

Also it would be nice to know if there is a chance to override basic behavior, without the need to change core files.

I hope someone can help me out

Thanks
