How many calories do I need?

I'll need to calculate my TEE first:

BMR (Basal Metabolic Rate) - Mifflin-St Jeor formula

Men: BMR = [9.99 x weight (kg)] + [6.25 x height (cm)] - [4.92 x age (years)] + 5

Women: BMR = [9.99 x weight (kg)] + [6.25 x height (cm)] - [4.92 x age (years)] - 161

so my BMR would be:

BMR = [9.99 x 68kg] + [6.25 x 172cm] - [4.92 x 22yrs] - 161 = 1485.08

TEE (Total Energy Expenditure)
BMR x activity variable

Activity variables
1.2 = Sedentary (Little or no exercise + desk job)

1.3-1.4 = Lightly Active (Little daily activity & light exercise 1-3 days a week)

1.5-1.6 = Moderately Active (Moderately active daily life & Moderate exercise 3-5 days a week)

1.7-1.8 = Very Active (Physically demanding lifestyle & Hard exercise or sports 6-7 days a week)

1.9-2.0 = Extremely Active (Hard daily exercise or sports and physical job)

Taking my activity variable to be 1.6 (I game hard, so I'm picking moderately active to suit that), my TEE would be:

1485.08 x 1.6 = 2376.128

What are my goals?
At first I want to lose weight before I start toning. No, I'm not overweight, nor do I wish to look as skinny as I did in high school (shudder), but I want to be able to see the progress I'm making so I'm doing to try to shed the fat first. If I'm wrong PLEASE tell me in the comments, I'm not an expert and am just trying to figure all this out!
To ADD weight: ADD 10-20% calories to the total above

To LOSE weight: SUBTRACT 10-20% calories from the total above

I don't want to lose a lot of weight, nor do I want to lose it quickly. So my ideal daily caloric intake will be:

2376.128 x (100-10)/100 = 2138.5152

So that's

2100 calories/day
