Could more experienced MFPers cast a glance...?

I joined MFP in December and have lost 5lbs which I don't consider too bad considering I didn't really take it all that seriously until very recently.
3 and a bit weeks ago I started being more mindful- I started the 6 week challenge on the Wii Fit EA Active more workouts which has helped me to actually do some exercise! I've also begun walking more often (and more quickly). My exercise routines are still a work in progress and I will be introducing more cardio, and continuing with my strength exercises 4 times per week (the EA stuff)- it's fairly low level stuff at the moment as I want to build up gradually.
In terms of my eating habits, they are getting better. I've never been particularly dreadful with my food except perhaps for the lack of fruit and veg- again this is a work in progress!
I've spent the past few weeks trying to do research into adequate nutrition, calorie intake, TDEEs etc etc, mainly based on the posts on here, links etc. I have found it very complicated as there is a lot of contridictory advice out there. I found the following page very helpful:
http://body-improvements.com/resources/eat/
This is a page made by one of the members of MFP (stroutman- I think that's his username, apologies to him if I have that wrong)

Anyway, I have formulated the following plan of action which I intend to start in two weeks when I've finished my first EA six week challenge. The main reasons for the delay are that I need time to plan my meals in order to get my head round the change in macronutrient goals, and to be honest, it feels weird starting it half way through my challenge!

So my plan (which is really the bit I would like opinions on is:
A daily calorie goal of 1290 (net)
Protein goal 93g per day (372kcal)
Fat goal 53g per day (478kcal)

This is based on the following:
Current weight- 152.25lbs
Height- 63 inches
Lean Body Mass- 93lbs
Body Fat %- 38.9
BMR (Katch-McArdle)- 1283kcal
TDEE (sedentary)- 1546kcal
Daily Calorie goal therefore- 1290kcal (as I can't go below my BMR, I plan on adding all exercise and eating all those calories)
Goal Weight- 133lb
Goal Body fat- 30%

So, what've I missed/ done wrong/ got confused with...?
Any input would be great. My diary is open (I think) but please bear in mind that I've not been doing this plan yet!
