Wht don't you use LVM (Logical Volume Manager) instead of some many
partitions? The advantages of LVM are the following:
- You can easily resize a logical volume. However, resizing a
partition is not as easy.
- You can implement N logical volumes using a single partition.
However, you need N partitions to implement N volumes.
- There is a maximum limit on the number of partitions. However,
although there are theoretical limits on the number of logical
volumes, in the practice rarely you max them out.

You can do fine with a single swap partition.

This shouldn't case any problems, as far as the swap signature is
retained (AFAIK the swap signature can be removed when using
suspend-to-disk) there shouldn't be any problem. And, in case of
problems, you swap partition won't be activated. Later, you can use
mkswap to re-create the signature on it and use swapon to activate it
