Dear FSWON,
(1) Ok
(2) Ok
(3) No. Mention only those items currently in your possession and you plan to bring it to Canada. Serial Number is more important than model number. And also mention their approximate value in CAD. If you are going to buy laptops before landing, you'll definitely be having those laptops with you. So, write down their serial numbers in Goods to Carry list. You must declare your Goods to Follow list upon landing.
(4) Before departing, update your Goods to Carry list and only write those jewelry items which you are bringing with you. The ones you are not bringing, or are planning to sell, can be added in Goods to Follow list. It's not mandatory to bring all the goods mentioned in Goods to Follow list. There is no such thing as 'actual move' when it comes to immigration. The day you 'land' will be written everywhere in documentation.
(5) That depends what you tell CBSA officer upon landing. There is no tax for the money you transfer from other country to your bank account in Canada for settlement purposes. You don't have to declare in advance about the money you are planning to bring (transfer) in the future. Declaration is required if you carry an amount exceeding CAD 10,000/- while you land. Once you land, you become permanent resident. If you decide to move permanently after two years, you must ensure you fulfill 730 days (2 years in every 5-year period) of residency requirement.
Note: If you leave Canada before your arrival of PR card, you may not be allowed to board any return flights to Canada.
