this depends on your network LAN speed, if 1Gig or 100Mbps, and if you have PoE devices like IPphones etc,,and the budget you have ..
from your network, you can use any of 2900 series (L2), i recommend 2960
or you can go to L3 switch 3500 .. i recommend 3560

I would go with a 2960S full gigabit to all ports and inter-vlan routing if required.
Will 24x gig ports + the 7x 10/100 ports on the ASA be enough?

WS-C2960S-24TS-L  Catalyst 2960S 24 GigE, 4 x SFP LAN Base  
WS-C2960-24TC-L  Catalyst 2960 24 10/100 + 2T/SFP LAN Base Image  

Standard CAT5e patch cable between the ASA and the 2960 switch

Be sure that you get the ASA with enough user licenses (10, 50 or unlimited) and DMZ. I recommend the Sec+ with unlimited user license.
ASA5505-SEC-BUN-K9  ASA 5505 Sec Plus Appliance with SW, UL Users, HA, 3DES/AES  
Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

I know this could be another question but according to the diagram I provided for you.
Can I just configure E 0/1 with network and place a linksys switch and on port E 0/2
with network and place a linksys switch?

Yes, that will work fine but if the two networks need to talk to each other, be careful of the license on the ASA5505 because most options restrict communications between the vlans. The Sec+ does not restrict it.

I need the two networks to be completely separate as they are 2 different businesses(One is investments and another Insurance but in the same office) so I think it will work fine.
Now Do I have to assign the same security level to E 0/1 and E 0/2.

No, you can assign e1 default inside security level of 100 and e2 as level 99 if you want
