I'd just buy a good set of spanners and sockets - I changed my axle last week and by the end of the project I had loads of sockets and spanners out, 8, 10, 12, 13, 15, 16, 17, 19, 22, 24, 34... deep sockets, normal sockets, combinations of extension bars, 3/8 to 1/2 drive and vice-versa etc...
You really need a decent set of tools to do what you suggest including cutting tools, vice grips etc.
I use a set of 8-19mm ring spanners and have open-enders in the 20-30 sizes.
I use 1/4, 3/8 and 1/2 sockets, in the 3/8 and 1/2 drive I have normal and deep. Hex and bi-hex are also essential, I have a good selection of extension bars, enough I can create an extension about 4 foot long if needed, getting the wings off needs at least 15-20inches of extension. You would also benefit from some big philips driver bits, ones that go on a 1/2 drive are great as you can lean in hard and ratchet them out.
My first kit should have been over £100 and it had most of the sockets and ratchets in it, think I paid £50 on a good sale. It's taken me a long time to get to where I am now, but think of the money you are saving doing all the work, I think you ought to bite the bullet and get a good selection of kit. Sounds like you are doing a fairly big project for your first (I assume this since no tools).
