Take AIM and BUILDUP use them as often as possible.
Think about slotting sets with a global ACC bonus.
Regarding the accuracy issue, part of it is likely indeed your level. If you're playing on teams, they've probably got the difficulty cranked up - are you fighting a lot of red and purple enemies? Those colors denote higher level or rank foes, which can be harder to hit. For solo, try talking to the hero corps representative and making sure you're set to fight only even level enemies.
This issue will be at least partially resolved shortly, however. At level 22 you can begin to slot single origin enhancements (aka SOs), which are much stronger than the dual origins you're probably using right now (you can buy SOs in talos island). A pair of single origin accuracy SOs in each attack will be enough to ensure good hit chances against up to +2 level foes without much trouble, as long as there aren't any defense buffs or accuracy debuffs going on.
Also, keep in mind that aim and build up (which are called psychic focus and concentration in these sets, but are the same otherwise) both give a bonus to your chance to hit when you use them. They only last 10 seconds each, but that's plenty of time to toss off an AoE or two or a volley of single target attacks, and if you only use of of them each time, they should be up relatively frequently. These powers also give pretty significant damage bonuses, so they're staple powers for most blasters. If you don't have them already, do consider picking them up at some point and giving them a couple of SO recharges each.
In terms of enemies resisting your damage rather than you simply missing, that's just a fact of life. Everyone runs into *somebody* who resists their type of damage once in a while. Enemies that resist psi damage are only moderately common, but the things that do resist it tend to resist it a lot, so it can sometimes be annoying. The most common culprits are robots (other than clockwork). The best weapon you have against resistant foes is telekinetic blast, since it does a goodly chunk of smashing damage as well as psi.
In terms of enemies resisting your special effects, keep in mind that, other than subdue, your blasts don't have 100% chances for these effects to occur. TK blast only has a 60% chance for knockback, and will domination only has an 80% chance to sleep. Additionally, while knockback resistance is uncommon, boss, elite boss, and archvillain class enemies get additional protection against mez effects such as sleep and immobilize. In general, it'll take two or more applications to affect these foes. Also, if a controller on your team uses certain mez powers against foes, those foes will often be rendered immune to knockback for a short time (this is meant to represent the fact that, if your opponent is encased in stone (for example), it's kinda hard to knock him flying).
Mostly, just hang in there, it gets better once you can slot SOs. The mid teens to early 20s are a bit of a slow patch for many characters.

This is what it means to be a tank!
Related to accuracy, try this:
1) On your power tray you'll see the word "Powers" next to Inspirations and Enhancements. Click this and a list of your powers comes up.
2) On top of your list of powers you'll see the words "Combat Attribues". Click this and another window appears.
3) On this new window, click on "Base". This will show you some base stats for your character.
4) One of these stats reads "Last Hit Chance". Right-click on this and choose "Monitor Last Hit Chance. This will make a little window that shows you what chance you had to hit after every attack you make. You can close the Combat Attributes window but keep the Last Hit Chance one open. Drag this window somewhere convenient.
5) Go fight stuff and check out what your chance to hit is. 95% is the highest it goes. If you are still missing too much at 95%, unfortunately that's just a streak of bad luck (yes it happens to all of us). If it's always lower than 95%, you can use accuracy or tohit buffs to improve it, or lower your difficulty level.
Note that some enemies have specific powers that make them harder to hit; pay attention which enemies these are and what power is dropping your hit chance. Try to use a mezz power on them before they can use that power.

I've got me a lil' 20 blaster, who's a Psy/Psy build. I've only been playing for a while now, but no matter what I do, I can't seem to stop missing attacks when fighting enemies, either by myself or with people. On top of that, a lot of my snare or knockback effects are resisted, and I've no idea how to correct the issue.
I've stacked a great deal of accuracy enhancements on my character, but there are still a lot of misses and resists floating around whenever I fight. Is there any other way to remedy the situation, or do I just have to wait until I get a bit stronger for this situation to naturally help itself?
