Do not delete now but hear me out:

Will my posts and threads still be visible when my gos forum account is deleted?

[deleted] Yes, they will remain visible except your account which shows as the OP will be replaced with "[deleted]".

If you don't mind me asking, why do you want to delete your account?

When you see "[deleted]", that user's forum account has been deleted.
