I agree with Shikishima -- OOO or MMM+OOO is probably a good first step. (That said, I do feel like the difficulty of installing FCOM is often overstated, and FCOM was the first mod I installed when I first started playing Oblivion on the PC.)
However, to more specifically address your concerns:
Most mods work fine with FCOM, as long as you're using a bashed patch (which you must be, to use FCOM at all). Of the mods you listed, I am currently using All Natural, Better Cities, RAEVWD, all the Unique Landscapes mods, and the HGEC body. I also have a considerable array of minor tweaks, along with some more significant overhauls (RBP, LAME, Deadly Reflex, Enhanced Economy), quest mods (Kragenir's, Ayleid Steps, and Integration are the big ones), and graphical improvements (QTP3 Redimized + all of Mikal33's textures and a bunch of others). I have no FCOM-related issues. I am far from the only one with a setup like this. Using FCOM does not preclude you from using other mods.
I don't personally use Midas Magic, but I know that quite a few people do use it along with FCOM. It is highly likely that some of the MM spells can be used to make parts of FCOM less challenging than they are really intended to be. But so what? It's your game, play it how you want. MM won't "break" FCOM, nor vice versa. They're not incompatible.
There are patches required for compatibility, for some mods, but they're usually obvious if you read the readmes. For equipment additions and quest mods, the patches are typically things intended to restore balance. FCOM rebalances the game significantly, and that includes changing the stats of most weapons and armors. One thing that may be a problem is installing lots of individual armor or weapon mods. These will typically be overpowered for an FCOM game, and the small ones usually don't have patches to bring them in line with the rest of FCOM. But, again, so what? If you're having fun, then screw it, especially since you mentioned that you don't care about making the game super difficult.
As for the HGEC body, by default the FCOM armors will not be built to fit it. They'll look weird. However, the http://www.tesnexus.com/downloads/file.php?id=24078 has addons for FCOM. If you install that, all of the FCOM-added equipment will look just right.
All of that said: be aware that FCOM will significantly change your Oblivion experience. It's not for everyone. (On the other hand, I would never play Oblivion without at least OOO or TIE, if not all of FCOM.) If you have not already done so, be sure to read http://www.gamesas.com/bgsforums/index.php?showtopic=820948&hl= for an idea of what you're getting youself into.
EDIT: Realized that my last paragraph sort of implies TIE is part of FCOM. It is definitely not. I'm just saying that I need an overhaul to make Oblivion playable for me, and TIE or OOO are the two smallest mods that I consider sufficient. FCOM is built around OOO, and retains most of its balancing changes and core philosophy, but adds a ton of content by allowing Fran's, Warcry, MMM, etc. to be merged in. I adore FCOM. However, it is worth looking at your other options, and of those I consider TIE to be the best alternative. You may prefer it.
