Windows 7: Couple questions(syncing,exchange,windows 7 diff versions)

Hi

I have a work laptop and a home computer.

My home computer has Windows 7 ultimate 32 bit edition.
My work laptop has Windows 7 enterprise 64 bit edition.



Right now I bring my laptop every day home with me and it kinda sucks as it is heavy.

When thinking about it I have most programs already installed on my home computer except for a couple

Outlook 2007
office comunicator 2007 R2

That's basically it.

So I am thinking if I can get a couple things setup I don't need to bring my laptop home anymore.

Both of those programs use exchange so am I able to set something like that up on my home computer? I can connect at home to my companies VPN so I should be able to get exchange information???

The next problem is I usually place documents and stuff on my desktop. My company does give me some network storage so I could store them on there but if I could have my desktop syncing with either this network storage or desktop to desktop that would be great.

Like say if I have place a document on my desktop it would automatically put it in the storage drive.

Or if I could have my home computer desktop always sync with my laptop that would be good do.

Of course if I did it from desktop to desktop I can't have the files stored on a 3rd party server since I have to think about that being hacked and losing important work documents that could be bad if they get out(like me maybe losing my job).

Also that probably means I would have to leave the laptop 24/7 on and I don't know if that would be good for it the laptop.

I also lose one my security messages(my laptop is encrypted with truecrypt on bootup).

If it is just on 24/7 then it would be at the windows screen.

The other plus is if something would happen and my laptop is on I guess I could remote desktop on it.

As you can see I have lots to think about but I really want to try to get my home computer setup as close as to what my laptop is setup as so that I don't have to take it home every day just for that off chance that I need to work from home because of some unexpected reason.
