First question:

>> ls
file
>> split -a 1 -d file
>> ls
file x0 x1 x2 x3 ...

However, you will get

split: output file suffixes exhausted

with this method if there would be more than 9 split files. You can use

>> split -d file
>> ls
file x00 x01 x02 ...

and then use rename:

>> rename 's/^x0/x/' x0*
>> ls
file x0 x1 x2 ...

Second question: Use

split -a 1 -d file ''

if you will have less then 10 split files. Otherwise, use

split -d file ''

and then

rename 's/^0//' 0*
