Anything inside an IRA/tax deferred account can be sold without incurring any taxes on cap gains. So get those accounts out of the way ASAP - once you figure out what you want to hold across all the accounts (your asset allocation).
The brokerage is subject to tax if you are above (I think) the 12% taxable bracket.
https://www.bankrate.com/finance/taxes/tax-brackets.aspxMarried filing jointly caps at $80,250, so that would mean if you combined make under that then you could start selling anything you've held longer than 1 year as long term cap gains up to that ~$80K cap and pay zero dollars (as long as you don't go over anyway on anything else). If you do, then that money over the amount is taxed, so you'll need to figure out a schedule if you will be paying taxes on LTCGs until you get it all moved into the funds you want to hold long term.
Check the fees on the funds to buy and sell too. You'll want to make sure whatever you end up buying is the best for YOUR brokerage as far as no fee, but you can't do much about the fees for selling if there are any depending on what junk your adviser put you in unfortunately.
Once you've fired the manager, the main thing to do is to turn off any automatic reinvesting in the brokerage accounts on all the funds held that you're planning on dumping. This prevents future short term lots being created, so you can start moving/selling from the oldest and hopefully by the time you reach the front of the line (the newest lots) you'll at least minimize the short term cap gains you'll have to sell off.
And another note: you may want to examine the best most tax efficient funds to hold in your taxable. I hold ONE mutual fund in mine and use my tax deferred accounts to hold the bonds and such so they can generate dividends and other junk til the cows come home but don't pop my tax owed up at all. You want low turnover, low dividend generation as far as I've understood.

In my case, I use Fidelity, and just discovered that they use average cost basis as their default so that means I don't have exact cost basis unless I want to dig through the paperwork and report them myself (I don't). It isn't a huge deal for me as we were talking a few dollars difference and they report their info to the IRS. My understanding is that before 2012, it was on the individual to track their funds and that sounds like a nightmare. Average CB can work in your favor depending if things are up or down when selling and whether you are buying over a long period of time it can smooth a bumpy ride out, but you do want to make sure you understand the pro/con of whatever their default CB is so it doesn't surprise you when you go to sell.
