Question about front bumper/rock slider suspension requirements and hidden winch vs front bumper

Hello all,

For my next couple of upgrades I'm looking at getting a front bumper or hidden winch set up and some rock sliders. A few questions and some qualifiers:

My truck and what I'm planning on doing
2020 TRD OR Manual 4x4
1. Running 265/75r16 Duratrac AT's
2. I'm not really looking for a lift at this time as most of what I do is 2 tracks to get to remote lakes.
3. Looking to add a winch for self recoveries.
4. Looking to do some more overlanding. Possibly building an overland trailer in the near future.

Questions:
1. Is Aluminum worth the weight savings over steel? I've recently bought a roof rack from Victory4x4 and have been pretty happy with it so I was looking at their bumpers and rock sliders as options. They can make at least the bumper in aluminum (not sure about the sliders), and I was thinking about going that route. It's about 500 bucks more but about half the weight.
2. When I get both, will I need to get a heavier duty suspension or should stock be able to handle that additional weight?
3. Is a hidden winch a good option to save some more weight? Or is it at a point that it's not going to make a difference and I might as well just get a bumper?

Thanks in advance.
