Ok not read the rest of the thread in detail.. but!
Sub: If you can afford it I would recommend it, the front speakers in my car would sound too weak without it.. but you will need an amp for this. If you have a limited budget and don't plan on playing it loud then yeah you can go for a cheap one from a good brand (don't go for a cheap one from a crap brand though). 10 or 8 inch are good at this price level.
Cable: Personally I would replace the cable. The OEM cable in my car was incredibly thin and not up to spec really. Also remember you will have to wire up a crossover, so you WILL need cable for that.
Speaker quality: Expense doesn't just buy volume, it buys sound quality. Just because some speakers are rated to 150w doesn't mean you can't run them off 30w quite happily.
Basically a good guide to getting 'decent' car audio is to look for manufacturers who are honest about their specs. If you see an amp which boasts 1000watts for 50 quid, it will be crap. Better to go for something which quotes 75watts for 80 quid.
If I think of anything else I will add later
