My accountant charges me RM300+ a year for my business tax return service. I just leave it to him to do everything. No headache.

True. I paid RM650 for the tax accountant service each year. This fee also can be used as company expenses. Tak pening kepala.

in my case, YES! 

1) Form B, due date 30 june
2)i) - apportion out the INTEREST only. eg. your house has 3 rooms, ur business assume to use 1 room. so its 1/3, it depends how you explain to the tax officer. paying rental, messy because its another source of income and another set of computation need to show tax officer when they audit you.
ii) Messy, unless you get yourself and accountant or tax agent. because of the hire purchase, CA claim rules etc etc.
iii) Parketing ticket = as other forumer said, identify them, then its 100%. if you are lazy to do so, just claim 2/3 of it as business use, 1/3 as personal use. same goes to toll.
as for petrol, sorry to say theres no 100% for you, max 2/3 is for business 1/3 for personal use. IN ADDITION, you can add in upkeep for your car, well same 2/3 biz use 1/3 personal rules apply too.
iv) this 1 ar....to be safe, dont add lor.... if you really want then 50% max, dont 100%... because entertainment is too general in the eye of LHDN.
v) yes, electricity bill of your house. but same rules apply here, apportion according to % as your rental or loan interest.
