The term 'uprated' is so broad it's essentially unanswerable unless you describe what the car will be used for. This is the rule of thumb I use for suspension modifications:
1. General use as a utility vehicle, some greenlanes, towing infrequently, packing up with partner/kids/dogs/friends etc for camping I would say use stock genuine shocks.
2. If the car is going to be fitted with a winch and do allot of towing I would look to find some springs with higher spring rates for the weight and dampers that match. This doesn't mean increase in size BTW
3. Stock ride height will cover 95% of Greenlanes and off road tracks in the UK. If you are comitted to changing the ride, handling and cornering characteristics of your car because you have found that one road that requires some lift, go for the +2 inch suspension lift. Previous comment regarding towing, weight etc will determine spring rates.
4. If you want a rock crawler / look at me truck go for mad 4+ inch lift, body lift and truck tyres and accept the fact it will not go round corners.
Hope this helps.
