Need help, 1999 RSV1000 ignition and forks

I have ran into 2 issues that i need help/advice with.

1. 

I need to take the ignition barrel apart.

The barrel has been damaged (has something stuck in it) so i need to take it apart or replace it.

One of the bolts holding it on is a tamperproof one that the head has snapped off.

I have tried to use a dremel to make a slot thinking it could use a flat head screwdriver.

Unfortunately its still too tight (even using a 1/4 ratchet).

I have undone the top pinch bolts and centre (17mm hex) and the top fork holder is lifting up slightly, but not enough due to the brake hydraulic cables.

I have taken the front fairing/lights of the bike off for better access, but still proving difficult.

How do people manage to do this?

2. When i took the wheels off to put new tyres on, 2 of the fork pinch bolts for the front wheel snapped (one either side). 
I will probably need to drill these out, but this is almost impossible whilst on the bike (I have already snapped 4 drill bits trying).

Not only that, but the toffee allen bolts holding the front mudguard on are rounded. I have tried hammering a spline piece in to try and get some grip, but they are still not moving (3 of the 4).

I will obviously need to take this off if i am to get the front forks off to drill the pinch bolts out.

Also, how do i hold the bike up when the front forks are off?

The rear is on a paddock stand. I did think about an axel stand on the engine but it started to rock and was not safe at all.

Would it be best balancing it on the rear wheel, side stand and jack somewhere at the front?

Unfortunately i could not get out whatever it in there which is stopping the key going in, so i need a new ignition/key.

I dont need a new fuel cap or seat lock, just the ignition, but having trouble finding one (new or used).

I have sent AP a DM to ask if they have one.

I also bought the Abba stand that was being sold nearby, and may need to buy the front lift kit and fitting kit.

Although i have used a straight metal threaded bar that has gone through the bike and works fine, but i still need a way of keeping the front off the ground.

I could use an axle stand (or 2, to be extra safe) i guess.

I'm sure AP will help but two other ideas

1. Take the barrel to a decent locksmith who may be able to help repair it

2. Check out the parts search on AF1 (https://www.af1racing.com/2001-2002-Mille-Spare-Part-Catalog) which will give a good idea of cost and availability of new parts. The UK part number for "OEM Aprilia Ignition Lock Assembly" which is what you are after I think, is AP8102910 (no match) or the USA part is AP8124895 is https://www.af1racing.com/AP8104941-OEM-Aprilia-Ignition-Lock-Assembly---8104941 cost $213 plus taxes, shipping etc.

I'm no expert but hope that is of some use.
