Hi
I had one of those. You can remove the filter canister without the worry of a bunch of oil flowing out. Some will but not a lot (it would be a good idea to place a pan under it to catch the oil which will mostly come from the canister).
Once you have the canister removed, you'll need to unscrew it using a strap wrench (readily available at Lowes and you'll need 2 of them).
It gets messy from that point on as there will be oil inside the canister and surrounding the spin on oil filter.
I dreaded changing the oil so much that I designed (and now sell) a completely new type of filter.
You can see it here:

I hope this helps.
