No, it does not reset. But, DO NOT EVER reset the gachabox, unless it states "Alpha SR: 0/1 Beta SR: 0/1" when you still do not have those slayer cards.
The slayer cards are in addition to the other SR cards, which fall under the "SR Cards: X/21". So, you can have the gacha box state:
Alpha SR: 1/1
Beta SR: 1/1
SR Cards: 0/21 <-- this means the regular SR cards depleted.
Which basically means that the next SR you pull is guaranteed to be a slayer card!

Something I noticed: some people share their EGs every single time. I hit one, thinking they needed a hand, 3 minutes later they bring up a new one. A little investigation showed the persons' unmodified SED would've been enough already to bring it down, so, in other words, they were slacking their kills for some reason..

However, rules of thumb for phase 1:
1. If you can beat it yourself, then do beat it yourself, even if it takes multiple hits, it's more points to you!
2. Don't bother beating other peoples' EGs, especially not if they take way less damage to beat than a weak hit of yours! You get way more points from beating your own EGs and keeping your avarage damage per hit high.

-Getting the last hit in doubles the base points you get for the kill
-Dealing most damage doubles the base points you get for the kill
These bonusses are additive, not multiplative, so getting the last hit and being the one dealing most damage nets you three times the base points.

While the amount of damage you deal is limited by your SED, your main limitation in turning that SED into Event Points, is your Focus!
1 million SED equals 100,000 minimal damage on a weak attack (1 Focus)
100,000 damage equals 10,000 Event Points
Ergo, 1 million SED equals a minimum of 10,000 Event Points per point of focus

If you get the last hit /or/ deal most damage, then your 1 million SED suddenly equals a minimum of 20,000 EP per point of focus
If you get both the last hit and deal most damage, then your 1 million SED suddenly equals a minimum of 30,000 EP per point of focus

So, the trick to earning as much EP as possible, is to maximize the amount of EP you get per point of focus, and the best way to do that, is to both deal most damage and getting the last hit! Sharing your EG after only a weak hit, basically means you forfeit a third (last hit), possibly even two thirds (most damage as well), of your potential event points! So ask yourself, do I want 10,000, 20,000 or maybe 30,000 EP for that point of focus?

Killing off someone elses EG means that, although you might get that last hit, you will often miss out on the most damage bonus.
But, it gets worse when you're doing an overkill! If that EG needed only 50,000 damage to get killed, while your weak attack deals at least 100,000 damage, then you get only 5,000 EP for the damage, which may be increased to 10,000 or 15,000 EP for the bonusses. So you effectively got 15,000 EP less than you could've had for that point of focus.
Do that twice, and you're already a point of focus behind on your potential gain.

Now, some people share/help to help eachother out. Especially in phase 2, most of us can hardly get around sharing/helping to deal with the SEGs and to get their SEG-kill counter up.
But for phase 1? Seriously, no, it's not worth it, the Support Energy ranking rewards aren't that awesome to strive for a high position and waste focus on EGs that people could've easily killed themselves. It's good to help those who really can't handle the big EGs yet, and sometimes a friend has to go offline and "leaves it up for grabs", but I'm ignoring the ones who constantly share what they could've killed themselves.
