You cannot specify a charge rule with 0 for the amount. A charge rule will only ever add to the total for an order, it will not zero out the other charges.
You only need to setup the rule where you would like to charge a value based on the conditions. It seems that you have the first rule setup for this correctly. So if you have any items in your cart that have the prodType column set to 1 you will be charged the flat rate shipping of 2.00 regardless of whatever other items are in the cart.
For the upload limitations you need to ensure that you can upload the max size, and that the timeout is large enough for you to make the upload. So this part will depend on how fast the upload is occurring. If you want to upload a 10MB file but only have a 300kb upload rate it would take about 4.5 minutes or so to do this. So you need to set this to a value that will allow you to upload the size of file you need based on the upload speed of your connection.
1MB = 1024KB = 8192kb
