To do an oil and filter change you will need a 8mm and a 19*mm wrench.
The 8mm should be in your tool kit but the 19*mm is lacking.
While talking about tools, now would be a good time for you to invest in some of the basic ones and because you will need a 19*mm wrench you should consider buying at least a set of open end/box end metric wrenches.
This should include sizes from 10mm to 19mm and will probably cost about $20 if you have a Harbor Freight around.
A 8" adjustable wrench is also very handy to have.
A little write up I did about changing your oil is in this link
http://www.enfieldmotorcycles.com/forum/index.php/topic,10782.0.htmlThere was a time that the new UCE engines oil filter some loose spring loaded pieces under the cover and when the cover was removed a large brass washer, a O Ring between the washer and the filter and the spring would pop out as individual pieces.
Your 2010 might have this older design so watch for flying pieces.
If your bike has the revised filter cover, the brass washer and spring will be retained inside the filter cover which makes getting it back together much easier.
As for sorting out your electrical system, have a look at this post. It deals with protecting some of your wiring from sharp metal edges and IMO everyone who owns a Royal Enfield should make these fixes.

You will insert the key and try to turn it and nothing will happen.
The trick here is to press the cover right next to the key slot towards the bike.
Under the cover at the lock there is a VERY stiff piece of rubber that is there to keep the door or cover from rattling and until it is compressed the key won't turn.
After getting the cover off I applied some grease to the little arm that engages the frames tab and it helps to make unlocking the cover easier but even so a little profanity is often needed.
* edit- 19mm was 17mm
