Currency and Billing/Shipping question

Hi All,

I am setting up the store with Business in India but would like to receive order from outside india mainly USA, Europe etc.

Couple of Questions -

To keep things simple on Currency , I am thinking of having only one Currency configured Indian Rupee.
Does this makes it clean to maintain?

Also, i want to always have shipping address in india and mostly billing address outside india and use Paypal Express Checkout only as payment method (which i believe does not require registration to place the order).
Is all this supported in zen cart v1.5.0?

Also, when a US Customer checks out , cart will show amount in Indian Rupee but once it is taken to PayPal site , Does it show the amount in Customer's Currency?

Thanks in Advance.

yes paypal express is in zen cart but you will have to activate the module and fill in your paypal info. for it. if you set your site up to show only one currency then the customer will be charged that currency. they can pay using US dollars (for example) but paypal will convert it to rupees for you but I believe they charge a small fee for this.
