Help absolute beginner with sub interior creation

[Pistitom]

Hey guys, since there's no ,or very little chance of a modern day submarine game SH5 style, I started wondering about creating new interiors for these awesome cold war/modern day submarine mods. Played through SH3, SH5, so want to try sg. new ( DW proved to be too much of a challenge )
So, I've never done anything related to 3D modelling nor textures, mip-map, render etc, and other alien things, so, need a little help here...with the basics, some tutorials, video, or pdf, etc...
I guess 3ds max (or sg. else ) and photoshop are necessary ?
thank You all in advance for any info, help on this.
This will be the rabbit's hole for me.
cheers
