To insinuate that after such a short time doing weights with very minor resistance that your are now "big" could be construed as insulting to people who would hack off a limb to put a inch on our arms/legs/chest/back within that timeframe.
As correctly pointed out, you have a "pump". This happens in a major way during exercise and lasts afterwards to some extent as you repair your muscles and build more. The only way to track progress is with a measuring tape and you are unlikely to see any major change in your body shape while working out as the change is so minor. It is worth noting that psychology plays a big part in self-perception here, always get a second, third and forth opinion (reddit's r/progresspics can give you some indication/help).
Thank you for setting your targets clearly. Those goals are achievable but you need to understand what the 'real world' implications of those goals are.
Goal 1: Smaller Figure
How to achieve: Monitor your calorie (and macronutrient) intake and simply eat less than you use up. Websites like IIFYM.com can help you set your target calories and apps like myfitnesspal help you track daily.
Goal 2: Toned body
How to achieve: This is achieved with increasing muscle size and decreasing body fat. Tone is a myth, it simply doesn't exist, you only have fat and muscles. To achieve the "toned" look you need to have a balanced program of lifting weights and cardiovascular exercise (Ask here for a program if you want!). Pair that with a diet to reduce your body fat percentage and you will get the "toned look".
Side Note: Soreness
This is called DOMS (Delayed Onset Muscular Strain). Basically, you did something your body isn't used to and your body is working overtime to repair itself, it is not a injury; if you go for a 5 minute run you may notice that the ache vanishes as blood pumps round your system. Keep training, warm up and cool down properly and they will pass with time.
