If your character is busy doing something as a 1 round+ action, are they able to still take advantage of AoOs?

Unfortunately, you can't.
Bodyguard reads:
Benefit: When an adjacent ally is attacked, you may use an attack of opportunity to attempt the aid another action to improve your ally’s AC. You may not use the aid another action to improve your ally’s attack roll with this attack.
So, it would be "No, you can't", as Bodyguard need an especific kind of action to be performed (AoO) and the Total Defense Rules states that you can't use AoO's while in Total Defense.
The rationale behind this is that while you are in Total Defense, your only concern is protecting yourself. To "be a bodyguard" can be seen as protecting someone else, so you can't really be on "Total Defense". You can look at Fighting Defensively (Scroll down to it) as an alternative to this. It won't provide the +4 but it will provide a nice +2 on your AC that can be really helpful.
You are right,
Some first level spells are not (that) useful for first level characters
The combat rules for measuring the duration of effects (including spells) state:
When the rules refer to a "full round", they usually mean a span of time from a particular initiative count in one round to the same initiative count in the next round. Effects that last a certain number of rounds end just before the same initiative count that they began on.
(emphasis mine)
Unfortunately for our first level casters, this means that when they cast a spell which lasts only 1 round, it will fizz away immediately before they get a chance to use it.
So, why would something like this even be a Level 1 option?
First of all, there are several exceptions which makes such spells useful even for a first level character:
- Touch spells allow you to "hold the charge" until you successfully hit with them, and give you a "free" touch attack attempt as part of the action of casting the spell.
So you can attack on the same round you cast them, as well as keep trying to hit for as many following rounds as you need. - The spell is still active during other combatants' actions on that round - both enemies and allies - this may come up when:
- Your spell can counter an enemy's action - for example, casting Unbreakable Heart on yourself will protect you from a Fear spell your enemy will cast during his action.
- You cast the spell to buff an ally (such as Sun Metal cast on your barbarian friend's axe or Unbreakable Heart cast on a confused ally, allowing him to take his turn normally)
- An enemy exposes himself to your attack of opportunity (your Sun Metal will be active and enhance your damage during his turn)
But, most importantly, some first level spells are mainly useful for casters of higher levels - but it is still better that they are first level spells, because:
- You can access them earlier - for example, Sun Metal may be cast by a 5th level ranger (caster level 2), if it was a second level spell, that ranger will have to be at least 7th level to cast it.
- You can cast them more times per day - sticking with Sun Metal as an example - a 7th level ranger can cast it 2 times per day, instead of just once if it was a second level spell.
- They don't "compete" for spell slots with the more powerful second level spells - at the end of the day, you probably wouldn't want to trade a casting of Brow Gasher or Wilderness Soldiers, just to gain the benefits of Sun Metal - it is not powerful enough to justify being a second level spell, and if it was, it probably would have never been selected by any ranger.
Hope this helps you making sense of it all...
p.s. - I'm not even trying to discuss whether casting Sun Metal is ever the optimal choice for a ranger of any level - you didn't seem to ask about that, and I normally don't care much about such issues myself, so I may not be the best user to tackle that...

No, you can't. Because you don't threaten enemies
Core Rulebook, Combat, Full-Round Actions, Cast a Spell (page 187) says:
Since you are casting a spell for the full duration of the round, you are not finished casting the spell until the start of your next turn (possibly longer depending on the casting time). This means that while casting a spell that takes 10 minutes (ie: Divination), you cannot make Attacks of Opportunities for 10 minutes.
Attacks of opportunities are usually provoked when an enemy does certain actions while inside your threatened area:
