Comparative animal distribution datasets

Hi,

I have downloaded CSV occurrence datasets for voles and kestrels in the UK, then displayed the XY data of each as points using the latitude and longitude. Not sure if this is the right place to post but I have a few queries

1) Is there any way to remove certain points? They are very large datasets and I only wish to investigate England and Wales - although I have data for Scotland and Northern Ireland as well. I could only come up with a painstakingly slow method of trawling through 10,000 odd points based on their co-ordinates. Can I somehow delete the XY data points?

2) Is there a better way to depict the populations other than clumps of dots?

3) Is there anything cool I can do with the data? (it's for an assignment - we've barely been taught GIS and I would like to get cheeky extra marks) I added locations of SSSI's (highest level of British protected areas) in England and Wales to the maps. Could I do some sort of analysis based upon that?  

Sorry for the long post and thankyou for all of your help :)

Rich
