The Iraq war I'll give you but that was Blair's personal desire to please George Bush, rather than party policy. Had it been Cameron, I've no doubt the outcome would have been the same.
Manufacturing output actually reached a record high in 2007, according to the ONS, so that one's bollox.
Holding gold reserves has no value as far as a government is concerned. It's a speculative asset and in fact the sale of such reserves was restricted by international agreement after that, as our sale drove the price down, not up. The subsequent rise was largely due to the knowledge that a large scale sale couldn't happen, except maybe under extraordinary circumstances. There was therefore virtually no downside risk in buying gold from then on.
The Millenium Dome was a crock of shit but it was originally the idea of John Major's government but was expanded by Blair's. The money came from the National Lottery (£600m) and sale of tickets (£190m) so not really public funds.
The money from the NHS had to come from somewhere. It either had to be borrowed or privately financed. Given that you said Labour borrowed too much, you can't have it both ways.
Unemployment had fallen from its peak in 1997, when Labour took power, up to 2008. Obviously the recession increased it. It's never come near the levels seen under the Thatcher government. So if you want to get on your high horse about unemployment, that's when the worst damage was done.
Under Labour, UK net borrowing reached a peak of 3.5% of GDP in 2004/5 prior to the recession. 2014/15 it will be something like 5.5% and is estimated to be be 4.2% in the current fiscal year. So if borrowing was out of control under a fiscally irresponsible Labour administration, how would you class it now, when it's supposedly under control?
I'm not particularly pro-European but let's not forget which party negotiated our original entry and signed the disastrous Maastricht treaty.
