Depends entirely on your travel style. This page should give you an idea:

and is this a good travel route?

Yes, except that I recommend visiting Kobe after Osaka and Beppu before Fukuoka.

mabey stay a few days at each give or take?

Some of the cities along your way, such as Kyoto and Osaka have enough attractions for a multiple-day stay, but others have one day worth of attractions.

thinking about takayama and kanazawa too??

Why not. Looks like you have the time.

should i add any places to the list or take any off??

Depends on your interests.

and also how much money will i need for this trip roughly?? on a pretty tight budget as im a uni student!!

I do not know about the route but the cities listed are good ones. Takayama and Kanazawa I have been there and if the weather premites by all means GO! Uji and others will help with your route. Money is always a good question. You could it cheap using youth hostles and eating at fast food places and even 7-11 but remember its Japan so dont forget to treat yourself to real Japanese food... Have a great time.

The problem is the weather.. cold,rain, and days are short. By 5 pm it is already dark. For 45 days you need a bare minimum of 50 $ a day if you stay in hostels (not including long distance transportation within Japan--2 JR passes plus planes to Sapporo will cost quite a lot--and from your country to Japan and back). This means about $ 2500.$ 3500 plus transportation would be more realistic. You could use night buses but only for a few trips. One month of travelling would be more than enough and a bit less expensive. After all few Japanese have ever seen their country from one side to the other.

thanks everyone..

i hought it would be able to get cheap flights from nagasaki to sapporo over the internet?? havnt really looked into it though..

is it really going to be that cold and rainy?? i read somewhere thats its still pretty dry.. in msome places??

also is nikko worth visiting for a day?? whilst in tokyo region??

It rains more in summer than in winter. I travelled around Osaka, Kyoto, Nara and Tokyo in February this year and there was barely any rain. There were a couple of days of snow while we were in Kyoto and Osaka but it was light and it added to the experience anyway.

Nikko was for me absolutely fascinating but then I am crazy about architecture and understand how much work was involved. Besides that the forest, lake, waterfall are pretty beautiful too. Apparently there is a saying: "Who hasn't seen Nikko doesn't know the meaning of beautiful" or something like that..the famous 3 monkeys (see no evil, hear no evil, speak no evil)are there by the way

One thing to note, it looks like you might be heading to Sapporo during the Snow Festival:

If that is the case then you will be lucky to find a hotel at a reasonable rate, or even find anything. It will probably be more expensive for air travel to that destination as well.
