I went to go to work the other day and opened the shed to find a small oil patch on the ground around the front wheel...

traced it back to the right fork where the 2 piston bits meet (where the little black seal is)
Im guessing the fork seals are shot and have lost all the oil out of the suspension and my question is... Is it hard to fix by myself or should I take it to the bike shop? and if I take it in how much would I expect to pay??
Also I think my chain is too lose there seems to be way to much play in the chain compared to what I have read about chains, is it hard to adjust?
Cheers
