First, the class is throwing errors because you have 1 class ability (Astral Skin) bootstrapping 2 other class abilities (Brawn and Improved Evasion). All class abilities should be bootstrapped by a Class Helper, Archetype, Domain or Custom ability. If you want to add some class abilities based on the current form, that could be handled by a script adding a Custom tag and bootstrap conditions, but that's a seperate issue I won't go into unless you need it later.
Alright, so on to the meat of your question. It doesn't look like your class has any Custom Abilities of it's own yet, so it should be fairly simple. On the Class Tab, scroll down to the section where it says "Custom Abilities", it should be about half way down. The first button is Custom Ability Count, click on that and open up the array. Row 0 is 1st level, enter the total number of "Evolution Points" or whatever to that row for 1st level. Row 1 is for 2nd level, enter the total number of points at that level. Go down the rows, adding the total to each one according to the eidolon point progression you mentioned. Remember that the Row number is 1 less than the class level it represents (so row 14 holds the information for Class level 15).
Once that is done, hit OK, and move to the next field "Custom Ability Name" and enter whatever the appropriate name should be (for summoners this would be "Aspect")
You can probably skip "Custom Ability Plural", if left blank we'll assume the plural just adds an "s" to the end of "Custom Ability Name"
If these abilities are Optional (that is, you don't want to throw a validation error if the character has points remaining unspent), then check the box for "Optional Abilities?"
Next Click on the "Allow Custom Abilities..." button, scroll through the list, and find "Summoner" and check it. There are 2 Summoners listed, click on the ? to the right and make sure you check the one with the unique ID "cHelpSum".
And that should be all you need to add Aspects to your class. Save the .user file and reload HL with ctrl-R or close and re-open. Test to make sure your class shows the aspects.
Other notes:
You appear to have gone through and clicked every Profession class skill tag. There is an "All Profession Skills" tag you can click instead, and a similar choice for each of the other "Skill groups". They are listed at the top of the skill lists.
