No, mate. having longer struts is no issue in the front (unless the length limits compression) because the limits of the suspension is defined by the bump stops.
The problem you have is with the coils. You need to understand that there are different ways in which a certain suspension height can be achieved. You can have longer, softer springs (which compress to the desired height) or you can have shorter, harder springs that don't compress as easily. Following this thread it would appear that you have the latter. It's not really clear whether they are constant rate or progressive (progressive being softer initially and then getting harder as they're compressed more). I suspect constant rate. This would explain the harsh ride, certainly in compression. Generally springs of this type are specified for heavy duty applications - heavy loads or a lot of heavy accessories all the time.
Certainly with a winch and bullbar you need heavier than the standard coils but your model, I believe, comes with the standard raised height coils, so not much heavier..
The real crux of your problems though is that you've attacked the issue the wrong way around. Time and time again new members ask the question and they're told to do their accessories first then only add suspension once the final weight of the vehicle is known. They're also told to go to a suspension specialist who can specify a setup and actually tailor it to the axle weights rather than just choosing an 'off the shelf' item, even if there are choices. As Snowman said, this is not because we're all in cahoots with a particular suspension manufacturer but is, rather, the benefit of the mistakes many, perhaps most, of us made in the early days of this series of the Triton. The initial savings were almost inevitably lost when we found that what we'd chosen just didn't work, or worse, failed.
Suspension engineering is an incredibly complex thing. It needs many years of experience with a specific vehicle to be able to accurately and consistently specify a combination of spring and shock absorber that will give optimum performance on a vehicle which is unique, even amongst its peers. The local mechanic or the counter jockey who's last sale was a set of wiper blades or driving lights just don't have this kind of expertise. Nor do they have the technology to build a unique combination tailored for your vehicle and needs. We are fortunate indeed to have a forum sponsor who has these capabilities but they're not the only organisation with this capacity. I'd suggest though, that they are unmatched in experience with the Triton and this also is an important point. What worked with a Land Cruiser, Patrol or Defender most likely won't work with a Triton. Brand loyalty is commendable but wasted if there is a better alternative.
I see that you now intend to talk with an independent suspension supplier. I think that really is the right move. Hopefully they can help you achieve what you need without too much expense.
