This bit was definitely easier.

<Lítilmanligt> is the adjective, not the adverb: '... and
said that it seemed to him unmanly to crouch thereat'.

It is indeed a sling; CV has the nom. sing. <slanga>.

I'd say 'by'; <með> here seems both instrumental and
locative, but 'by' implies 'with' and so covers both. (It
may be that from a contemporary point of view the
significant thing here is that K. wasn't fostered out.)

<Eldgröf> is a lexicalized compound meaning 'fire-pit', but
otherwise this is pretty much right: 'He lay in the fire-pit
and bit bark from the charred wood and watched his mother's
kettle'.

The verb is <sæta> in sense (2) in Zoëga, 'to suffer': 'They
suffered from him the most severe terms'.

'They had Þ., his son, take many messages to B. when he
would not sacrifice and called him Búi the dog.' ('Dog-Búi'
would be <Hund-Búi> or the like.)

'Þ. summoned B. before the þing for false belief and asked
that he be punished by outlawry.' (For the 'asked that' bit
see the last example in Zoëga s.v. <varða> (5).)

'He had always gone to B. to meet his father and mother, and
he did so still' (or 'and he continued to do so') probably
captures the actual sense a little better; tense usage just
doesn't always match up well.

Under the circumstances, 'coldness' seems a better choice
than 'melancholy': 'All of this brought about a great
coldness between the houses' (more literally, 'on account of
all this a great coldness occurred ...').

<Leið> here is the past tense of <líða> 'to pass', not the
noun; <líðr á e-t> 'the time draws to a close'. Thus, <um
várit er á leið> is 'towards the end of spring' (more
literally, 'in the spring, that was coming to an end'). <Er
þess getit> is simply 'it is said': 'It is said that Búi
went to Brautarholt as spring drew to a close'.
