From the mind side of things, everything is 'needed' except for Levitate, Total Domination, and Telekinesis. Any of those can be taken if you want them, of course, but skipping them won't really affect performance. While leveling, Confuse is your friend. Use and abuse it. Mass Hypnosis and, later, Terrify are your bread and butter mezzes for groups. Mesmerize can sleep bosses in 1 hit, also.
I'm not familiar with Thorny Assault, unfortunately.
As to your concerns for Perma Dom, getting basic levels of it isn't too difficult/expensive. Requires at least 75% global recharge and Hasten with 3 slots filled with Recharge Reduction IOs. I personally recommend shooting for 90% global recharge, at the least, as this gives you a decent buffer in case you forget to click domination or hasten.
Getting that global recharge can be pricey depending on how you go about it. Easiest way is to make sure you have 5 powers in the build that can take a Luck of the Gambler: 7.5% global recharge IO. there's 37.5% right there. This IO is really expensive if you get it off the Market. However, if you're diligent, you can just take the time to earn the various Merits the game uses as currency to get it that way.
If you don't have it yet, Google Mids Hero Designer. Download it, learn it, throw something together, and post it on the forums. The forumites will be able to help you evaluate cost and effectives of the build to fit your needs.

Wow ty cool ill hit up mids when I get home. Can some give a little help with thorns plz.
Getting relatively cheap perma-dom is simply a matter of slotting as many different recharge bonuses as you can, keeping in mind the rule of 5: no more than 5 of any one named IO bonus stack. The addendum to that is that its the name of the bonus that matters, not the actual value - which is why you could stack 5 LoTG+recharges (7.5% each) and 5 of the 7.5% recharge bonus given by Basilisks Gaze, as they are different named bonuses despite having the same numeric value. The following recharge bonuses and sets are relatively cheap (compared to purples, for example) and can be slotted in the following powers in a mind/thorn:
LotG +recharge 7.5%: These are not cheap on the market but can be picked up fairly easily by running hero/villain tip missions to earn alignment merits - it costs 2 alignment merits per IO. They can be slotted in any power that takes defense IO's - hover, combat jumping, maneuvers, vengeance, stealth, invisibility, grant invisiblity. The most common way to get several of these is to take stealth, invisiblity and grant invisiblity - that only takes 1 power pool and gets you 3 LoTG's.
The other 7.5% recharge bonuses can be found in the Basilisks Gaze Set and are very cheap slot wise as they only take 4 sltos, put them in dominate and total domination. You can also get them from kinetic crash (KB set, 6 slots), Sting of the manticore (snipe set, 5 slots) and mocking beratement (taunt set, 6 slots) but I don't think any of those can be slotted in mind/thorn powers.
Next are the 6.25% recharge bonuses, which you can get from the following sets:
Decimation/Entropic Chaos: Ranged damage, 5 slots
Positrons Blast: Target AoE damage, 5 slots
Call of the Sandman: Sleep, 5 slots
Malaise's Illusions: confuse, 5 slots
All of these can be slotted in various powers in a mind/thorn dominator.
Finally there are the sets that give 5% global recharge:
Crushing Impact: Melee damage, 5 slots
Obliteration: PBAoE damage, 5 slots
Doctored Wounds: Heal, 5 slots
There are actually a lot more, but these are the easiest to get and slot. Crushing impact will go in skewer, Obliteration in ripper and thorn burst and if you want to pick up heal other/self for some heals you can put Doctored wounds in it.
As a final note, mind control has the ability to slot the 2 purple sets that tend to be the cheapest on the market: Fortunata Hypnosis can be slotted in Mass Hypnosis and Coercive Persuasion can be slotted in either confuse or mass confusion. You want to slot some combination of all the above sets so that you have at least 70% global recharge NOT counting hasten. That is the bare minimum for perma-dom and it really IS bare - if you don't fire off hasten as soon as it recharges or if you get hit by any recharge debuffs you will lose domination. I find at somewhere between 85%-95% is where I get comfortable and if you can get to 120% global recharge you will have perma-dom without needing hasten at all, although I have not been able to do that even with a couple of purple sets in my builds.

It's actually 125% for nonHasten perma dom. My mind/psi runs with 120% preHasten and I'll just barely miss it refreshing.
