Linux Advanced Routing and Traffic Control

Hi all! I'm new to this list, and hope for some clarity in this matter:

I have a home-gateway with linux-2.6.9 and iproute2 (ver:2.6.9). My
following tc syntaxes.

# eth0 internet scheduleing are:

tc qdisc add dev eth0 root handle 1: htb default 20

tc class add dev eth0 parent 1: classid 1:1 htb rate 512kbit burst 6k
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 512kbit burst 6k
prio 1
tc class add dev eth0 parent 1:1 classid 1:20 htb reate 9*512/10kbit
burst 6k prio 2

tc qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10
tc qdisc add dev eth0 parent 1:20 handle 20: sfq perturb 10

tc filter add dev eth0 parent 1:0 protocol ip prio 10 u32 match ip tos
0x10 0xff flowid 1:10
tc filter add dev eth0 parent 1: protocol ip prio 10 u32 \
match ip protocol 6 0xff \
match u8 0x50 0x0f at 0 \
match u16 0x0000 0xffc0 at 2 \
match u8 0x10 0xff at 33 \
flowid 1:10

tc qdisc add dev dev eth0 handle ffff: ingress

tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 \ 
match ip src 0.0.0.0/0 police rate 2200kbit burst 10k drop flowid :1

# My eth1 schedule:
tc qdisc add dev eth1 root tbf rate 512kbit latency 50ms burst 10000

The long eth0 tc-script is fetched externally as you may see...but:

This have worked well for me (no, really) but...since I am a newbee, I
have read the lartc doc, and understood some but very much was really
hard to get...especially the class and filter stuff. Lets say it's not a
'for dummies' book :) No complainig. My Q are, is there a chance I will
get packet losses or other messes to gateway(eth1/eth0) if I have no
rule set for my LAN-PC:s? Or the above scripts for that matter...Should
I have a 'eth1 tc-command here?' Or any advice or comment would be
greatly appreciated.
