[sf-lug] partitioning/formatting USB memory stick

On a Raspberry Pi I'd like to use a USB memory stick (Kingston 64GB DataTraveler Micro) for extra storage space and am seeking advice as to how best to do this.

The first question is how to format it.  It's currently formatted for FAT:
Command (m for help):
Disk /dev/sda: 61.9 GB, 61872793600 bytes
32 heads, 63 sectors/track, 59943 cylinders, total 120845300 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x7eb36409

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *          63   120845087    60422512+   b  W95 FAT32

Command (m for help):

I'd like to use a Linux type file system- 
Which would be best?  ext4??

Another question has to do with partition boundaries.  I've read that it is best to have them line up with the way the read/writes are done and although this is not predictable, using a number such as 2048 is usually a good bet.
The question more specifically then is whether it is best to "Start" at 63 or to start at 2048 or some other number?

Alternatively would it be better to leave a shortened FAT partition at the beginning and make the rest of it EXTn?

Any advice would be appreciated.
