New here, I just bought a 56 plate 1.5dci estate at auction (more fool me

The immediate issues I have identified with my new car are:
- front electric windows are dead, had a play last night and cannot even hear a click of the motors, does this signal water ingress knackering the wires or a bigger problem? If its electrical I think I found new modules on ebay for £22 delivered, no doubt you guys will know what I mean
- when starting the car it states 'Auto Lights Disabled', pressing the button doesnt seem to turn them back on. No big deal for me, Ive never had such a feature before, but why is it doing it?
- Bonnet wont open. The lever inside offers little resistance, just sort of folds out quite nicely. The catch in the grille just sticks out enough for me to get purchase on it, and when I pull it nothing happens, except in the gap between badge and bonnet I can see it moving.I found this thread (viewtopic.php?f=2&t=20683) and I've got the passenger grill off and the (not so white anymore) rectangular honeycomb grill but Ill be damned if I can see anything to do with a bonnet catch in there. Anyone got any advice on what I should be feeling for? Pics would be excellent as I am not very mechanically minded
I think these are all novice DIY'er things to fix, I would rather not have to go to the mechanic to get these sorted as I can see it being a fortune when it 'should' be easy enough with some experienced heads to get it back to full condition again. I need to get the cambelt done as it has no history, but considering its done nearly 130k it's got to have had it done at least once.....right

That seems to be it for now, would appreciate any advice!
Thanks
