I didn't model the panel on the lower part, I may come back to it, but you might find this to be helpful.

When you make your revised model, on the bezel, bevel you corners with slightly more geometry (I think I did eight edges here; preferring powers of 2 can be very helpful.), and then add some extra loops running around the bezel. Square quads are your friend, as they'll make the shading look better when you cut holes in it. I made my holes with booleans, using cylinders with a number sides equal to the number verts that will surround them. For example, you can see that my holes have 12 sides, and the quads it occupies in the grid have 12 verts around their perimeter. This lets everything connect nicely (I would be happy to make a step-by-step with screenshots if you want).

As far as the protruding panel on top, the idea here is make your edges follow the form of the shape. You can see how my edges go at 45 degree angles at the corners. Subdividing this as it stands will cause it become an oval, or circle. But with the support loops, it will maintain it's shape much better.

The blue edges represent beveled edges. This is equivalent to beveling with ctrl + b. However, in this case, you can see Blender is taking care of it automatically with a bevel modified. You sacrifice a minuscule amount of control over you geometry in exchange for blender making managing your topo a bit a easier. Experiment with this, as it is very powerful. Often, support loops are just bevels in disguise. The bevels are often critical for maintaining sharpness in the shape. You can assign bevel weight to an edge in the CTRL + E menu. Also experiment with crease edges (again, assignable in the CTRL + E menu).

Also, note the positioning of the triangle. Place these in flat spaces so that when you subdivide, distortion from the triangle will be none, or very minimal.

Anyway, this topo isn't amazing, but I hope it gives you some ideas.
