It depends! If your old car has good fuel consumption (say 30mpg or better), doesn't smoke and the oil leaks can be stopped, then keep it. Even with a lot of replacement parts and welding, it's still better in terms of its whole life energy consumption than buying a new car.
If it uses a lot of fuel, is smokey (and can't be easily fixed) and the oil leaks are irreversible, then send it for scrap or reuse it for something else - making sure all potential contaminants are removed.
The tough decision then is do you either buy another old car in better condition or new? Personally, at this point I'd for another old car and wait to see what happens with hydrogen and fuel cell technologies.
Dual fuel, hybrids etc may be more efficient but they are still not a long-term solution and their production uses vast amounts of energy.
to use bleached but 100% recycled loo roll or unbleached but 20% recycled?
If you have grey water recycling and mains water, then get a bidet. And no, don't recycle the bidet water but by recycling most of your household water you can afford to use a little in your bidet.
Otherwise, look more closely at your loo roll. Is it oxygen bleached or chlorine bleached? (Oxygen bleaching is less bad.) Is it the really rubbish sort of loo paper than actually means you use more than a higher quality paper? Can you ration your use? (My parents used to restrict us to eight sheets when I was a kid - six person household and low income for many years.)
Are there other alternative loo rolls (eg unbleached and 100% recycled)? Remember, non-recycled is not necessarily "bad" - if the paper comes from European managed forests, almost all now plant more trees per year than they fell. Also, a loo roll with a proportion of virgin pulp will be stronger than a 100% recycled roll and so you may use less of it.
What's more important? A comfortable bum and a guilty conscience or a slightly scratchy bum and a clean conscience? No one wears a hair shirt because it feels good!!
to buy recycled by mail order or non recycled at the local shop (this obviously may depend on what it is!)
Persuade your local shop to stock recycled! But, whether you you buy recycled via mail order or non-recycled at the local shop, the transport energy used is the same. Much better not to buy - if you can! A better question is whether to buy from a small business (whether local or mail order) or from a big corporate business.
to spend money on alternative energy etc (which in the majority of houses can take a long time to payback the cost) or to simply use as little energy from existing sources as possible and donate money to a worthwhile eco-charity?
A bit of both. As energy prices rise, so alternative energies become more cost effective but choosing to go green should not be seen in simple economic turns. If you believe we should be using less non-renewables, then you will use more expensive non-renewables so long as you can afford them (even if cutting down in other areas of your budget).
You should be aiming to use less energy as well, even if that actually means the payback time on your alternative energy sources then becomes longer. Why? Because you're going green because it's morally right, not cheaper.
I don't donate to eco-charities as I believe I can make more difference closer to home, a large chunk of the donation will go in admin, and I support them by either paying a membership fee and/or buying their goods and services in preference to those from big business. So, I buy from the Organic Catalogue and am an HDRA member, but I do not give them donations.
I'd say the main thing is to tread as lightly as possible. Do without as much as you can and within reason, re-use as much as you can, use as much recycled as you can, and only buy new products when you have to. And if you have to buy, buy local, buy from small businesses and source from as close to home as possible.
Of course, it's easier said than done but life without challenge is boring.

PS And remember, don't get too hung up about the problems. Being green is as much about having fun as it is about saving the planet. Leave the doom and gloom to the consumerist masses doing their clockwork jobs. (And my apologies to the Ishers who have to live more in that reality than we do!
