Fine Tuning Small Scale Quad Recipe

Hello,
I am trying to brew a small scale batch Quad using a partial extract method. I have a method right now scaled down to 1 gallon, but I might bring it up to 2.
I figure I should keep it simple so this is my current set up:
Note that I am planing to order from Northern Brewer so that is why I have these particular items here.

Dingemans Aeromatic Malt - .3 lbs
Dingemans Biscuit Malt - .3 lbs
Mutons DME Light - 1.2 lbs
Millards Amber LME - .6 lbs
Czech Saaz - .2 oz (60 min)
German Perle - .2 oz (60 min)
Candi Sugar - 6.5 oz (5 min)
Corn Sugar - 1 oz (Flameout)
3787 Trappist Yeast (half the pack)

I am sort of new to this, this is only my 5th session. I know a few things from researching, so I wanted to compile a more concrete idea before I committed.

So I was planing on steeping the grains at around 153 F for an hour, then getting the wort to a boil and adding the DME and LME. I was gonna let that boil for about an hour and add in the hops as specified above. I have read that I should add the Candi sugar slowly over the fermentation process, so I was wondering if I should do the same with the corn sugar or if I should just leave that for priming. Also, should I get any nutrients to the yeast during fermentation?
I figured I will keep it in primary for about 10 days and the bottle condition it for around 2 months. I know the more time the better but I want to have this up and running for Christmas.

So are there any tips or tricks that I should look into before doing this? Any help would be tremendously appreciated.
