Any experts here? I have a Q?
Pension advice is a regulated area, and legally advice can only be given by those qualified to give it. No professional advisor is going to stick their neck out and give you (or anyone) advice on t'interweb without reviewing your current situation, future ambitions, appetite for risk yada yada, because they would end up being be fined millions by the FCA. That's why I keep saying that if you're asking these sort of questions then you really should go and see a good IFA - you get regulated advice with the backup that if the advisor screws up you can sue for mis-advice.
That said, what I would do is....
I would leave any defined benefit pensions be, and take them how they were supposed to be taken - are you saying £10K p/a or the transfer value/'cash in' value is £10K? If it's 10K p/a then this is basically 'gold plated' and guaranteed for life (or whatever terms the pension has). Even if the pension fund goes bust the Pension Protection fund will step in and continue paying most of it.
I would take every last penny of the 25% TFLS from the defined contribution pots. It's all tax free (up to £260K or there abouts), and you don't want Rachel from accounts to screw you over. Put as much as you can each year (currently £20K p/a) into ISA investments, again before Rachel from accounts moves those goal posts..
Draw down the remaining 75% of the DC pension pots to meet your income requirements, remembering that your DB is paying £10K p/a and the state pension will be £12.5K p/a. So you have about £23K p/a drawdown available before you hit the £50K 40% tax band.
The other 'trick' if you want to retire before your State pension age is to start taking £12.5K ish from your DB pots between ages 57 and 67. Then at 67 stop taking money from the DC because your SP will replace it.
There are other things you can do (TFLS recycling

, deferring your SP, etc), but these are quite advanced things that again an IFA can advise you about.
