unless you need the stacking capabilities of the 3750, go with a 3560 24port 10/100 or 10/100/1000. configure etherchannel between the 2950's and the 3560 with at least two links. force the 3560 as the STP root. add another cable between each of the 2950's for redundancy.
"Which device do you think that would be the most appropiate? Maybe a 3750 switch would be enough?"
Depends on what particular model 2950 you have, and whether you need your backbone to support L3.
For instance, if you only need L2 and copper ports on the backbone switch, the 2960G-8TC-L might work for you if your 2950s have gig copper uplinks.
If you need L3, and again assuming gig copper uplinks, you could use either a 3560G or 3750G, or might even be able to use a 3560-8PC with the above 2960G-8TC-L. (The 2960G-8TC-L ties together the six 2950s, and the 3560-8PC in a "router on a stick" configuration.)
Yes, you could obtain 8 SFP ports if you stack two 3750s with 4 SFP ports each. Note, some 3750s only have 2 SFP ports. Also if you go this route, you might want to obtain the non-"G" version to reduce cost.
Another switch to consider is the 3750G-12S, which offers 12 SFP ports. This might allow dual Etherchannel links to the existing six switches. It also, I believe, is the only 3750 model that offers a special aggregation configuration template.
Since you're not interested in L2, if you use either a 3560 or 3750, use the basic featured version, again to minimize cost.
