What Andy just said!
While Lenormand can be used for shorter spreads, and exercises involving paired combos and shorter readings can be helpful, Lenormand really shines and makes the most sense in the Grand Tableau! You can start by focusing on what is directly around the Significator and a particular topic (for instance looking mainly at what surrounds the money or the relationship cards).
As to meanings, I've 'collected' them for a long time - both from what's come up in readings and what others have suggested. But, what I keep coming back to are the original c.1846 meanings as they are the ones that seem to consistently give the truest and most to-the-point interpretations without all the modern suppositions that we tend to add on (not that those can't be true, too - it's just easier to get off base with them).
