These are just two examples. Obviously you can't stick in any noun, but I
don't know if these fall into some well defined class either.

Anyhow, are there any difference in nuance when formulating yourself one way
or the other?

I'm also wondering about the negative:

> ~する予定がない
>
> ~する予定じゃない

question
nuances
(noun) です vs. がある when either is appropriate
I kind of feel like です is more personal, more set, whereas がある (or はある) is
more distanced, more nebulous or open to change. (I'm actually more
comfortable with はある; I think it sounds a bit more correct, or likely.)

Consider です. 青いです means "It is blue", period, and that is a fact. By contrast,
using ある instead of です implies a little less personal investment in the
statement, to me.

Let's consider そのつもりです and そのつもりはあります.

If these statements are in the first person, then そのつもりです implies (to me) a
confidence that it WILL happen, while そのつもりはあります sounds a little less
confident (or more open to change) or just more distanced (perhaps in an
effort to be humble).

If someone were looking to change your mind about plans you have, and you
answered そのつもりです, it would sound to me like you're against changing your
plans, or (at worst) in favor of your plans and not sure why you should change
them. If you answered そのつもりはあります, though, it would sound a little more
receptive, to me.

If these statements are in the third person (a third party is the subject),
then そのつもりです implies (to me) confidence that those are the other person's
plans, while そのつもりはあります might imply that you believe those to be their plans,
but perhaps you're not greatly familiar with those plans, or perhaps not
greatly familiar with the person and don't feel comfortable speaking so
strongly for the other person (again, humility you could call it).

As for the negative examples you gave, I feel like they're just talking about
separate things. (I'm going to substitute その for ～する and は for が again, for
simplicity/my comfort.)

> その予定はありません  
>  (I) don't have those plans. OR Those are not (my) plans.  
>  その予定ではありません  
>  Those are not (my) plans.

Now, the second translation for the former looks like the latter, but..."my
plans" in the former is "plans that I have", whereas "my plans" in the latter
is "THE plans that I have".

The former is expressing: you suggested a plan, and I don't have that plan
(though I may have other plans). The latter is expressing: you suggested that
I have plans and that they are X, but the plans I have are NOT X.

But, of course, the disclaimer...I'm not a native speaker, so I could just be
imagining some of this. But I guess that's in part what the voting system and
comments are for. Speak up, Stack Exchange!

answer
The structure affects the difference in the meanings.

> ...つもりだ  
>  'my will is such that ...'
>
> ...つもりがある  
>  'I have a (partial) will such that ... (but I also may have another
> contradicting will)'

This results in that the former has more determined meaning than the latter
(as SomethingJapanese observes).

This difference in meaning also explains what Chocolate and gibbon discuss in
the comment. Unlike `つもり` 'will' or `予定` 'plan' which may or may not be
strongly determined, `はず` 'being ought to' is strongly determined by nature.
Therefore, it does not go well with the weaker expression `がある`, whose
implicature that it is "weakly determined" contradicts with the "strongly
determined" meaning.
