You can try The Boarding Co http://hakuba-rental.com/rental-prices-english.php
to get some idea.

I will be taking my ski lesson with Evergreen Outdoor Center in Hakuba http://www.evergreen-hakuba.com/japan-ski/...ssons-home.html
and there's a 10% discount on rental equipment from The Boarding Co

Budget per person per night?? I'm quite familiar with Hakuba, go there every year.

Which airport are you flying into? Chubu or Haneda/Narita?

For single traveller, quite a lot of options. Cheap dorm room starts from 3,500 yen, sharing with 3 other people. Shared toilet. If you want something nicer, can stay in nice B&B / lodge for around 8,000-10,000. Top end ski-in ski-out is 18,000 per night.

If you're bringing your own gear, then you can consider shipping it to your hotel from the airport, unless you're going straight to Hakuba.

If you're a boarder, then you consider staying in Goryu/47 instead of Happo-One, its more boarder friendly.

Hakuba is popular with gaijins so plenty of English signage, and almost everyone will speak English. You won't have problems getting around.

However, it is a very spread out town, so location is key. Make sure your accomodation is either:
a.) Close to the town and slopes
b.) Close to shuttle bus stop
c.) Provides transport to and fro to the slopes.

Hotel Price can check Agoda.

Flight will be from KL to Nagoya.  at Nagoya Station take Shinano Limited Express to Matsumoto Station. Then change to Oita Line to Hakuba Station.

You can carry your luggage along, but full gear + luggage might be a bit of handful on trains. Depends on how fit you are haha.

Actually, since you're staying there for 9-10 days, you can also consider staying at 2 different places. 4 days each in Happo-One and another 4 days in Goryu/47 will let you experience more terrain.

And I can't really give you a recommendation without knowing your budget.

Food in Hakuba is generally of a very high standard, and not really that expensive.

Kikyo-ya for example serves really good sushi, and their Chirashi Don starts at 1500yen, with lots of sashimi. Definitely cheaper than anything in Malaysia, and far better quality.

You can google for the lift pass prices.

If you stay 4-5 days in each major resort then you wont need to use the bus much. Anyway the shuttle bus is free.

Just an idea
Do you plan to only stick to Hakuba?
Any thoughts of going Takayama?
Im no expert at snowboarding at all, but i had my 1st try at Takayama Arkopia ski-resort. http://www.arkopia.jp/
Maybe  Arkopia is not extreeme for you as its just a simple slope
But at Takayama, you can do a day trip to Shirakawago.
*From Matsumoto, you can take the Nohi bus to Takayama. http://www.nouhibus.co.jp/english/nagoya.html

When i was in Hakuba, i stayed at Hakuba Alps Backpackers. its run by a gaijin, so english is ok.
In Takayama, I stayed at Jhoppers Takayama
