There are 87 not including the England squad.
The average yearly pay for a senior squad member playing in the Zurich Premiership was £60,000 in 2005.

the average amount is 10 people on the squad
Sorry i don't have a definitive answer for you. Also, you have not specified whether you meant just in the premiership, or throughout every division in the country. I would estimate that the average footballer in the premiership earns around £25,000 per week. This would not include the whole reserve squad etc, just ones playing and on the bench. In the lower leagues such as the conference, they may be earning around £500 per week.

I believe its Tottenham, in fact I heard a stat saying that Tottenham has the most internationals than any team in Europe! I count 26 internationals in their squad (not including Under 21s, U17s, etc)

only 40% are English as of march 2006 - ie. 20 clubs * 25 per squad average / 40% = 200 players
On paper, 12 grunts (infantrymen) to a squad. In actual combat, the numbered almost always varied.
No one! Claude Makelele is closest, winning the Champions League with Real Madrid and the 3 English trophies with Chelsea, however he wasn't part of the France squad in 1998 but did reach the World Cup final in 2006.
