Making a game is not necessarily easy. That said, if you're up to the challenge, I can suggest some rendering engines. Take your pick or go for something else: the ones below are all free! They also all include tutorials for their use.
Irrlicht: Ridiculously easy to use for beginners, but it has some poorly written internals that limit the engine for more advanced stuff and some simpler stuff. It includes XML parsing support out of the box. It's still ridiculously easy and can provide some nice results.

Ogre3D: Much harder to use, however it offers tools for rendering using so many techniques and generating so many images it's almost ridiculous. It
can (but may not be) slower on older systems, though.

Crystal Space: I've heard some good things about this, but I've never used it. I've heard that it's harder to use for some things than OGRE, however it's
quite a bit more than just a rendering engine (which I can verify; it includes audio). Combined with CEL from the same website, this provides according to them a complete game engine.

Pure Direct3D: I do not recommend this unless you have a LOT of skill programming. If you have tons, then you can make your own engine that's specifically tailored to your needs. It sucks up time, though!

Pure OpenGL: Another disrecommended option, however like the above, you can tailor the engine to your exact needs, and this one is much more cross-platform! Plus I feel that it's a bit easier to use than Direct3D, but that's me.

Game Maker: Mentioning Game Maker here is heresy simply because their IRC channel has more activity than ours, but I'm going to mention it anyway. This is a combined solution offering everything you'll be needing, but I wonder how customizable it is and how its graphics look.

For Audio:
SFML Fragment
You can steal the audio bits from SFML and use them in your own game. SFML has a reputation for being extremely easy to use, but I'm not sure how well the 3D audio rendering does; I haven't used SFML in some time.

IrrKlang
This one
is not free if you're not making a game that won't be sold and so I've never used it. Apparently there are major similarities between this API and Irrlicht's AP in terms of the feel.

Crystal Space
I wouldn't know, but maybe you can rip the audio section out of Crystal Space for use for your own ends. Just a thought.
Pure OpenAL: This one is fun, but not necessarily the easiest pick. It's a quite a bit like OpenGL.
