[Though the image you attached "is all Greek to me," I couldn't help but notice that above and below the $4500 P/L Open is ($7523.22) and ($1053.40) with parentheses that would indicate deficits on an Excel spreadsheet—a sight that causes me to suspect I should still remain somewhat wary and cautious regarding options.]
Wise attitude. You should remain cautious.
A fairly good argument can be made in favor of options being safer to trade than stocks, but I'm not going to get into that now. However, I will suggest some rules for a beginner of the "if I could talk to myself a year ago" sort, and I would slap my earlier self silly if he didn't treat them as iron-clad:
0) Don't expect to actually understand puts and calls by memorizing those definitions. You won't, until you see and internalize how they move in an actual trade - and especially what happens as combinations of the two move from ITM to OTM (in and out of the money.) Get familiar with the definitions of the option greeks - at least delta, gamma, vega, and theta - but, again, don't expect to really get how they work until you have seen them in action, again and again.
1) Start by learning a couple of basic strategies from the sites I suggested - in fact, just start with the four vertical spreads - and run them in a simulator until you get the basic mechanics down and feel like you have at least some understanding of what's happening.
2) Get out of simulator mode as soon as you feel even marginally ready. Until you have skin in the game, you will get nothing BUT the mechanics. Real risk = turbo-accelerated learning on nitro fuel.
3) Trade small; stick to the $10-$35 price range. This gives you a notional risk of $1000-$3500 (the real risk is quite a bit less than that, but staying cautious means being aware of the absolute max even if it's overstated), and lets you see and feel what is happening as the price and the remaining time change. HUGE MARIO-STYLE POWER-UP: take screenshots of your trades, including the values of the greeks, as the trade progresses (more frequently as you get closer to expiration), and study them as they accumulate. A lot of the changes are interdependent, but you are trying to build a sense for the boundaries, not develop a scientific thesis.
4) Stay as safe as possible. By that, I mean trade only indexes (which have a very small chance of crashing to zero - much less than almost any single name), always use risk-defined strategies (e.g., vertical spreads and - when you feel comfortable with those - iron condors), and always close the trade before expiration.
5) Bonus: Learn adjustment techniques (rolling) for the strategies you're using, both their pros and cons and when to use them or to simply take the loss and exit the trade. Stops are not nearly as useful or reliable on options as they are in other types of trading, so don't expect them to protect you in most situations. On the other hand, option trades tend to move much slower than stock or Forex, so you usually have time to decide what you want to do.
Other than that - good luck, be decisive in killing off your losing trades, and have fun! If you have a certain bent toward playing with systems, enjoy learning, and like hitting the books, options can be a real joy. And - oh yeah, almost forgot - could even result in a positive P&L (who'd have thought?)
(Also: there's a number of smart options folks here on ET, and their advice is worth listening to. You just have to learn to distinguish those from the... surrounding noise.)
