for accommodation in london, dont expect to see anything below GBP75pw in zone 1 and 2. and please bear in mind, london is huge. from one end to another is roughly from KL to seremban. zone 2 is roughly in the range of 20-45 minutes to central london by bus depending which area u're going, so if u're staying outside zone 2 (3-6), u're really staying quite far away. it's not worth it if u convert the expenditure for transport. atleast u still can cycle from zone 2 to school, but not zone 3. especially not in winter

.
my suggestion is to find accommodations in zone 2. it's cheaper than zone 1 and not that far away.
i cant give the latest estimation on the expenses for u bcoz i dont live in london anymore, but 3 years ago i survived in london with GBP425 a month including accommodations. things u need to cover are:
i. electricity
ii. heating
iii. water
iv. internet
v. food
vi. phone/mobile
vii. london transport
viii. academic related (photocopying, printing, stationaries etc)
en suite basically says that the bathroom is inside/attached to the room. standard suite means u have a shared bathroom in a flat, apartment or hall. personal wash basins are a cultural thing. remember that the british dont bath as often as we asians do, so usually they just wash their face and all.
part time jobs are easy to get, but equally easy to lose it as well. the pay arent as high as most expects, bcoz as a student u're stuck with a maximum limit of 20 hours per week. meaning if u earn GBP5 per hour, u could only earn GBP100 per week. u think that's alot? wait till u see how much u need to spend
