I guess I have three questions:
1) Does this sound like a good idea?
2) If so, how should go about finding a suitable tracker fund to invest into?
3) Should I diversify my portfolio by investing in bonds as well?
Second post on here made me smile - gloom and doom about fund management / managers, but why not stick it all in property - nevermind that it's still a hugely over-valued asset class by most measures at least in the UK (which I assume is where you're based).
As to whether Pazienza or DD are right in whether to invest now or wait for a correction, who knows (although my
opinion is in Pazienza's camp) - market timing is notoriously difficult for long term investing. Pazienza was also right about fund managers. A bit like anything, some are poor, most are average, a few are excellent. If you don't know that much about the markets or investing, then paying someone 1.5% to do it for you doesn't seem unreasonable and you don't pay any more for a good fund manager as you would a duff one. You just need to find them...
First, try and be as tax efficient as possible - if you open an ISA this year (ie to April 5th) and one on April 6th, you can get more than £20k squirreled out of the way of the tax man. If you've got a missus, you can both do it and get £40k in ISAs in the next month or so. Also think about pensions, another source of tax relief.
Second, make sure you go through a discount provider, personally I'd avoid an IFA as their advice is conflicted, and they don't know much more than you would after a weekend of reading up. I use Hargreaves Lansdowne who are excellent, although there are many others, basically you should not have to pay any of the 4-5% entry charges that are commonly quoted.
Third, if you want a balanced portfolio (you mention bonds) then, you may be better off in a fund where the manager is making those asset allocation decisions as well, ie a balanced managed, cautious managed, or absolute return fund. Again, a personal view, but the Ruffer Total Return fund (or similar) is worth looking at.

Hope that helps.
