Heres a view videos you should watch... It helped me a bit. http://www.youtube.com/watch?v=J9K-PhNVeEk

Well, sooner or later, you will need to learn the Ruy Lopez. It is a MUST to learn theory on the Marshall Attack because you will lose if you don't. In other lines, you can familiarize yourself with the ideas such as the Nf1-g3 maneuver. Pretty much play 0-0, c3, and d4 in most lines and you will be perfectly fine. Just look at the position and make the natural move if you cannot remember the theory on the Ruy.



Yes, me.
I think you are right when you say that the chances of any 1500-ish player knowing 20 moves of Marshall are slim to say the least. And even if they did, you don't. Therefore you deviate, unknowingly, leaving them to their own devices - the devices of a 1500. No worries there.
Anyway, if you want to you can avoid the Marshall on any move really.
To start learning the Spanish I think the book Starting Out: Ruy Lopez from John Shaw (Everyman) is great for players up to 1800. Although it is skimpy on underlying strategy, it will give you an idea of what variations are playable (it's biased for white, but then, the RL is quite good for white).
What helps in the RL is that each move has a strategical point that sometimes is lacking in sharp tactical openings. It's basically a long fight by white to get d2-d4 in, and black preventing that or getting his own counterplay going. Meanwhile white wants to keep the two bishops (in the main line, not of course in the exchange). Once you know these principles you can actually play ten moves of Ruy Lopez without memorizing. After that, if your opponent hasn't deviated, you come to choices.

Sorry but I disagree. If you're playing against a sub-1800 player the chances that (s)he knows the necessary 20 moves of Marshall theory are slim. Someone clever enough to do will not be sub-1800. Then again, someone clever enough to be over 1800 will realise that memorising 20 moves of Marshall is pretty useless because the chances of encountering someone else of around 1800 playing these 20 moves as white are also pretty slim.
And if you, after all is said and done, do meet such a rare specimen, you lose only the first game. The next time you play one of the anti-Marshall-systems. Or 5.d3. Grandmasters do.

Looks good. Start there, and if after a bit of study you find you are missing important things, only then start looking for a book. That website has more on strategy than the book I recommended earlier!
Once the summer starts, I intend to spend some time reading How to Reasses Your Chess by Jeremy Silman, as well as his book on endgames. Once I am done with that, however, I would like to play the Ponziani and the Sicilian less frequently and instead learn how to play the Ruy Lopez for both colors. I intend to get used to playing this opening by playing unrated games to get a feel for it. However, I need to learn how to play it in the first place. Is anyone willing to post a detailed analysis on the Ruy Lopez, suggest what variations I should use, and tell me what you believe is the best way to learn openings like the Ruy in general?
