a day in the life of hair extensions

i am 99% sure i am going to take the extension "plunge" and wanted to hear from veterans in re: to daily routines and care. 
1 - before, during, and after shower
2 - how often to shampoo and condition (recommended products)
3- styling techniques  and what products to use and those to avoid
4- how to wear at night (braid, ponytail)

my daily routine is to shower in the am, using shampoo and then conditioner on ends (nape of neck down), use a wide tooth comb after shower, towel wrap it, apply makeup, take hair out of towel, apply a leave-in condition on ends, use dryer (round and paddle brush), flat iron the unruly pieces and hairspray.  i have a habit of playing with the front pieces and side pieces during the day but pretty much leave the back alone.

what do i need to alter or add to my routine?

TIA

doing the SO.cap but haven't decided on the warm or cold fusion.  yes, i wash my hair everyday.  tends to get oily if i don't.  was told that i could wash the top of head (own hair) but not extensions everyday.

I wash my hair almost every day.  I treat it pretty much the way I treated my pre-extension hair.  Only difference is I do wear a braid to bed.
