The HP ProCurve is a solid switch. What model 1910 did you get? the -48 and -24 I’ve used and have had no issues with. The -16 I read of a couple firmware issues but that is probably fixed already.
The Linksys E4200 I’m not a big fan of but at the same time there aren’t any consumer routers I really like. The few people I know with a Linksys E4200 are happy with them.
In terms of your Intel NICs….not all Intel NICs are equal. For instance the Intel PRO/1000 GT PCI is crap.
