> 1) I will be working 9 to 5 and wondered if there are Estonian language classes in evenings or over the weekend? Something slow and not too intensive (I am not good at learning new languages).
If you need any material I've been told that this might be a good book - http://www.routledge.com/books/details/9780415450546/
You might be able to get it delivered from here - http://www.amazon.co.uk/gp/product/0415450543 (they have a Kindle version as well) or any other shop.
May I ask you what's your native language? As far as I know most of the language schools teach you Estonian if you're Russian native, so a book like that might be your best option.
> 2) Are there sites which collate information on goods (price, cost of delivery, etc) and present it in a nice format (such as www.salidzini.lv[1] )? If not then which are the better online goods stores in Estonia?
Is this what you are looking for?

> 4) Are there any online grocery stores such as www.coles.com.au[3] ?
