Question About My TDEE and BMR and Losing Weight

Ok I have a few question that hopefully you smart group can clarify with me. . .  Let me just start out by saying that I only plan on losing weight at the current time, I am not interested in builing muscle right yet. .  Also I think that for a 27 year old and 5'10 ish and I weight 195lbs. . . . .  I should be around the 180 mark is this correct??

Now with that being said. . .  I have looked up my information and I want to just see if I am reading and understanding it correctly. . .  From the calculations I got my BMR is 1998. .  My TDEE is 2892 (I put in moderatly active). .  and 3218 (if I put in heavy active). .  On average I burn about 650+cal/day and go to the gym about 5-6 days a week. .  I do 1 hour of cardio (which would be the 650cal) and then I do some chest and ab excersize (so I really don't know how many cal I burn there). . . .  I would like to try to go 2 days a day Monday, Tuesday and Wednesday if I can go depending on work. .  So those days I would be burning roughly 1300cal. . . .

So I think I am rougly eating around 2000-2300 cal/day. . .  I pretty much well eat the same things everyday so I can keep track of my calorie intake easier that way just until I loose the weight I want then once I lose it I will adjust my diet/eating habits as time goes on. . .  Right now I really don't want to change what I eat to much. . .  So my first question is am I eating the right amount. .  From what I understand I should be eating less then my TDEE but more then my BMR. .  So if I say burn 750cal/day then I should be eating roughly 2400cal is this correct (judging my the higher TDEE amount of 3218). . .

My next question is. . .  I am not a big eater really so I might not even eat the some days. .  IF I eat less then my BMR and still go to the gym will I still lose the weight or will this screw up my body. . .  Like I am talking short term for this while I am trying to get rid of the last 15lbs or so. .  Not long term as in make it last forever like that. .  Or what if I eat more then my BMR but less then my my calorie intake I need for weight lost will this effect my weight loss. .  I mean if there is a 500cal different between my BMR and my Weight Loss Calorie intake does that make a differnce if I don't fill that extra 500cal??

Any help would be appreciated. .  I would acutally like to loose the 15lbs by mid Feb but I know that your not suppose to loose more then 1 or 2 per week. .  Which would be I would need to loose about 3lbs/week until the date I would like to loose it. .  Not healthy I know so I wont even suggest that I would do that. . .  I have lost about 30-35 since August. .  So I guess that would put me in around 1. 5/lbs per week (maybe more cause I have been stuck at 195 for a few weeks now). . . 

Anywaz any help would be great. .   Thanks
